I would like to buy a BFL ASIC miner, but I'd like to run the numbers once they start shipping and can give a reasonable delivery date. If the ROI starting in January is 260 days or so, I wouldn't mind getting a BFL single. The idea of getting a 100% ROI in less than a year sounds good.
How did you get such high ROI-%? My own calculations would give only around 30% ROI on first year.
