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 (
)?
