Speaking of eBay, the sold Avalon6 prices are approaching an average of $300 each!
Due to the age of those miners, recent difficulty increases, new miners coming out, and eBay risks, is it worth it to consider these anymore, or should I just wait until I have enough for a 741?
I would say it depends on how much they cost and your cost and availability of electricity. If you are running them 24 hours a day on electricity purchased from the power company - you will be better off with a 741. If you are running 6 hours a day on surplus or free electricity of some sort, they could be a better choice. You have to do the math based on your individual situation - but for most full time miners you will be better off with the 741.
All depends on your power outlay. If you can afford a bunch of them, vs 741's or s9's (821)...that's where you have to decide how much buying those are vs buying something newer.
Thanks, guys. It'd be on 24x7 @ 8.5¢/kWh (4.5¢ supplier + 4¢ distributor) from the power(hungry) company, which is why I'm almost talking myself into waiting for an 741 since they're effectively half the power consumption per TH.
