i Purchased multiple units.
2xLittle SC (upgrade from jalapeno), 2xFPGA Upgrade and 2xSingle SC. That's 300Ghash right there.
First order in july i think, full expecting they will not deliver early on, infact, i was thinking of getting FPGA but knowing they will take 6months to deliver even those, i went for the SCs to get in the early batches.
Yes, i worry sometimes will they deliver or not, but the Risk VS Gain ratio is for myself was so far in the black i decided to go for them, infact, i made 2 purchases during this month. (1*Single SC, 2*FPGA Upgrade)
For offsetting the risk on ASIC i also spent on bASIC and ASICMINER. Was considering Avalon but they looked too scammy, and seeing they have delivery issues as well, and the unit is something i can't definitely operate at home, i'm kinda glad i didn't even attempt to get into batch #1.
When i see more proof i intend to purchase couple more Single SCs, or going for Minirig, partly from the Single SC profits and partly from ASICMINER divs+selling those shares when above 1BTC/Share which i expect to happen within 1½ months. The ASICMINER shares i got, if i sold them right now i could probably purchase already a Minirig, but i'm not really too keen on putting down that kind of money on BFL just yet, i want Single SCs in my hands first.
Also during the summer i will move my mining gear to a datacenter. Secure and climate controlled.
bASIC has yet to refund or even reply to me.
and yes, BFL sometimes worries me, but i try not to stress over it.
In hindsight 20/20 i didn't purchase enough ASICMINER shares early on, should have for higher offset on risks, but ASICMINER is that much opaque i didn't want to really. In the end, that was all that remained from GLBSE fiasco (Gigamining, what a scam). All other shares were a complete loss for me (probs 60BTC+ worth) as i'm yet to see any divs, refunds etc. from any of the other shares.
That's how i tend to roll, if i'm making an investment i want to offset the risk by spreading the whole investment in multiple choices, so if one goes downhill i still have something else and not complete loss. That strategy has well paid off so far, in BTC and IRL investments.
Why choose BFL? The FPGAs are *finished and polished* product, easy to use, just plug it in and let it do it's work. I hate the other FPGA products because you need to purchase power supplies, casings, fans etc. you just can't plug'em in and have them going on. for bASIC i had to order in some power plugs up front etc. and full knowing it's going to be messy setup. I want my setups to be tidy.
Nevermind that BFL's offer is on the better side on power efficiency, thus their lifetime will be longer, therefore profits are bigger, and cooling expenses lower.
I shut down my GPU farm last summer, it was too much work to keep it all stable, messy, noisy and too power hungry. One of my GPU rigs even burned due to bad chinese PCIe connector
Plus the final nail was when i blew 3 5850/5870 GPUs within couple of weeks and the replacement cards had severe heat & stability issues (purchased locally 2nd hand from gamers). at once i had 5 fully outfitted GPU rigs running, with total of 16 GPUs running, and 5 GPUs sitting on shelve waiting for me to bother to assemble another one. Today it would be worth to power it all up again tho, and been thinking maybe i should boot them up again until little scs arrive
