Buy used ASICS in a few months

[dr4]

Hey,
I don't pay for electricity. Therefore, mining would be a good idea for me to make money. However, I cannot afford more than a single HD 7870. In addition, when the difficulty rises, this will not work very well. However, would it be a good to idea to wait until even the ASIC mining is not profitable and then buy these used ASICs? If only few people are still interested in these devices, they will become very cheap, isn't it? When will this happen? Are there many people buying AVALON ASICs or are they waiting for BFL to deliver (  )?

Well, people may want to sell their low end ASIC machines to get the high end ASIC machine, but this will not be anytime soon?

If I'm not mistaken and an 66GHs AVALON Unit needs ~450KWh/Month that would be ~$130/Month (how much does the KWh cost in the US?). So the Difficulty needs to be 150x for not to be profitable. O_O

Soooo ~60,000GHs x 150 = 9,000,000GHs
Well umh, yes...
And the $/BTC will probably raise.
