I have 2 singles for sale that have been running rock solid for a few months now. I'll accept reasonable offers but lets get the ball rolling at $750 a piece plus shipping.

I will only be accepting bitcoins as payment and we will use the MTGOX last price at the time of sale.

Isn't BFL selling singles for $600 a piece right now?  Why the $350 premium for a used single?  ??? I feel like I must have missed a memo

Singles can be bought for ~63BTC from BFL, but shipping will take 50-60 days, based on current estimates.

The advantage of buying one second hand is that you can be mining in just a few days, instead of in 2 months.

That said, you can only hope to get about 10BTC a month, even at the fastest firmware. That means you will mine ~20BTC in two months.

So you can pay 95BTC now from cletus, and mine ~20BTC in the next 2 months, or you can pay ~63BTC, and mine nothing in 2 months.

So at the end of 2 months, you can either pay 75BTC, or 63BTC, your choice.

And based off this math, used Singles are only worth ~800USD (Price of a new one + 2 months of mining).

Hows this for proof?

Is it just me, or do those look a little dusty (http://www.amazon.com/Innovera-51505-Compressed-Gas-Duster/dp/B000U08SYK/ref=sr_1_1?ie=UTF8&qid=1346782065&sr=8-1&keywords=can+of+air).

haha they do appear that way but they're not nearly as dusty as they look in the picture.

At the rate difficulty is rising, I'd be surpised if you make 15 BTC in 60 days. If these were brand new, that puts them at around $750 break even. Used Singles aren't worth more than $700 at this point IMO.

That would mean difficulty would double in the next 30 days. Do you really believe that will happen?

$1,350 for both.  Cash money. 

With ASIC testing, anything is possible. Regardless, we are talking a difference of $50. With no difficulty increase at all, the most you are going to get is 20 BTC. Yochdog's offer looks good, I would take it. I'm thinking the market is going to be flooded with singles within the next 30 days going for sub $600. Not everyone is upgrading to ASIC.

BFL is getting their shit together. Shipping times potentially under 40 days (https://bitcointalk.org/index.php?topic=77796.msg1160312#msg1160312). You're actually looking at a BFL product in 4-6 weeks, people. This puts them at closer to 70BTC.

Crazyates I think your initial analysis is pretty accurate.  $800 is a fair valuation so I will accept offers for that price.

i'd take it

except you'd have to add $20 for shipping

be careful, YD will drop the cash!!!

LOL

I think i will stay on the porch on this one, cant run with the big DOG.

$1400

$800 a piece is really the best I can do.

Both have sold. If anyone is interested I can sell 3 more for $850 each.

I see a lot of these BFL single posts so I thought I would provide some input.

Buying used and having immediate delivery:

-$850 initial cash flow
(10BTC @ $11) = $110 x 12 months = $1320 total positive cash flow
Discount rate: ($1320-$850)/$850 = .55294 / 12 = .046078431 = 4.6078%
Net Present Value: $466.05
Internal Rate of Return: 7.520%
Projected 1-Year Profit: $470



Buying new and waiting two months for delivery:

-$600 initial cash flow
($0 x 2 months) + ($110 x 10 months) = $1100 total positive cash flow
Discount rate: ($1100-$600)/$600 = .8333 / 12 = .0694444 = 6.9444%
Net Present Value: $494.29
Internal Rate of Return: 8.844%
Projected 1-Year Profit: $500


$820 is the price at which the 1-year profits become the same ($500). Even then, the potential buyer must take into account the risk exposure he/she is subjecting themselves to.

Also, with the BFL SC products supposedly coming out next month, these things could potentially end up being worth hardly anything. Just my two cents.

except for trade-in

LULZ!  You are expecting to make $110/month?  First of all, it's closer to about $104 assuming you aren't paying pool fees.  But in case you forgot about difficulty, I'll remind you that there is no way you are going to be making $110, $104, or even $80 a month for 12 months.  Oh.. and in case that wasn't enough, there's this other little thing called block reward halving which is currently expected in about 2.5 months.   ;)

Srsly, why are you trying to look at a 12 month window? There are too many unknowns after the ASICs hit and the reward half. Instead, lets focus on what I mentioned earlier, a 2 month window. You compare what a used Single can earn in the time you would wait for one from BFL, and add that to BFL's sticker price. That's the value of a used Single.

A Single can be bought from BFL for ~60BTC. Their recent shipping numbers have been seen as low as 40 days, but lets go with a 60 day shipping to be safe. Any used Single will make ~10BTC / month. Over the next 2 months, that's not going to change drastically. In about 3 months, that will (ASICs and Reward half).

Buying used (after 2 months)
-$850 initial cash flow
(10BTC @ $11) = $110/month x 2 months = $220 total positive cash flow
Projected cost of time after 2 months: $630

Buying new (after 2 months)
-630 initial cash flow
(10BTC @ $11) = $110 x 0 months = $0 total positive cash flow
Projected 1-Year Profit: $630

Bump. 2 more for sale at 750 each obo.

I Purchased 2 singles from Cletus. They arrived today and are in great condition. Excellent seller!
