I'm about thinking about pulling the trigger on some scrypt mining and can't decide so I'm fishing for some opinions from anyone who is willing to share.....


SF-28M (Lee Group Buy) $2999
http://oi61.tinypic.com/2vvopw6.jpg
Power Consumption: 440W
Hash Rate: 28MH+
Chip: ??
Case Material: N/A

or

    GAWminers Falcon $2250
    Hash Rate: 27MH+
    Case Material: Aluminum
    
Chip: 55nm GAW Miners dedicated ASIC Scrypt (QFN Design)
    Power Consumption: 1040W

Gawminers is cheaper and comes with extras but the additional power consumption is a turn off.

Anyone know anything about the SF-28?
Any owners of the Falcon care to provide a review?

how much do you pay for power

difference between gaw and sf is 450kwh per month

lets say you pay 0.25 usd per kwh thats 110 per month

will take 7 months for the gaw miner to burn the 750 difference in price

both miners will be worthless before then

run the numbers through any profit calculator and youll see

Profit calculators are only useful if you sell the coin as fast as you mine it.  If you find a coin you have faith in for long term value it doesn't do so well. 

I have very little input on the 2 items though.  That power consumption varies wildly.  Are they both plug & play?

If you do power in your ROI. Your best options are the A2 and SilverFish miner's.  Silverfish have some great feature's considering price point. 

Also on resale I personally believe A2 and SilverFish will be worth more.  Month's down the line who willl want GAW or Hashra with power needed.  With A2's and SilverFish it will let you mine longer profitable if you pay for electricity which most do.

For a brief overview of features on SF miner take a look at https://bitcointalk.org/index.php?topic=514758.msg7308353#msg7308353 I also made a guide that goes in more detail.

Since my first post the Falcon price has dropped to around $2000(week five)-$2400(immediate) vs $3000 for the SF. Plus the father's day sale currently going on that being said... Now what?

I pay about $.07 for electricity.

I don't sell my coins but I do resell the hardware. I don't keep anything for longer then 3-6 months so desireability on resell is some what important.

My main concern with the SF is that is it so new to the market with little support or reviews. I don't want to be left tweaking it and getting everything peak and stable for the first week or two. You could say mining is a constant game of improving but new hardware tweaking vs one month old hardware tweaking are totally different games.

$2000(week five) vs $3000, est: 12,000 D. around release date...

I imagine resell value depreciating more on the Falcon vs the SF. I don't see the savings on electricity being worth it. What do you think?

If your elektricity costs only 0.07USD and only 3-6 months mining, then buy Zeusminer 28Mhash or their clone (GAWminer)

Out of these 2 GAW is much better, if anything goes wrong they are offering full support and refunds.
