I'm considering buying the Antminer S1 used on ebay for 99-120$. The S1 has 180-200GH and I think that this would be a good entry level miner. I do not pay for electricity so power consumption and efficiency are not factors in my decision to buy this miner. My only concern is that 180-200GH's is not powerful enough to actually output a significant profit. The mining caculators suggest that I should receive about 150-180$ per year but could this miner being slow prove some problems for me. Thanks!

Also that is a crap miner sold at a ridiculous price. I can't imagine it being worth more than its weight in scrap. You should be able to buy a S3 for that price. But no its not a problem per se, except reaching minimum payout from pools. Or a minuscule chance of finding a block solo.
