Looking to buy your old, dusty, used USB miners to solo mine with for fun.

I'm looking at around 5-10$ per unit (this depends on quantity and quality).

This is below the Ebay price hike but since i will be mining with them until they die and not reselling, I'm not prepared to pay $50+ for a 330MH/s Block Erupter.

So far i am unable to find any at a reasonable price, after contacting Bitmain and Canaan directly they have none lying around (I guess it was a long shot).

I'm looking for:
Antminer U1
Antminer U2
ASICMiner Block Erupter
Avalon Nano
Bitfury Red Fury
Bitfury Nano Fury

I will accept any condition, but the price will reflect this.
