I know my two cairnsmore1s are still working hard and I have hit my ROI so it's time for an upgrade, count me as +1.

if you are looking to get some thing now and not play the asic game, i'd look at the FPGAs that are out there and see what works for you. i have two of the cairnsmore1's and i have loved them. but there may be better thing for what you are looking for,

more info on cairnsmore1 https://bitcointalk.org/index.php?topic=78239.0

or if your looking to go all the way.

by useing glasswalkers hashvoodoo you can let each fpga find it's best settings and run most any core at over 220 MH some up to 230

i run two cairnsmore1's at 1.8 gh, I have found the hash voodoo bitstream to work the best with MPBM

HI i'm trying to get to be able to post on the FPGA page.
