Should I buy an 060 card from there, I'd feel morally inclined to sell my 030 card for a reasonable price of £30-40 with RAM, but, who's to stop the person I sell it too from dumping it on eBay and making a profit out of it?
If that site and others like it are made aware to the entire Amiga community it'll stop people overcharging (to a degree), but, it's going to affect those people trying to sell the hardware they bought at a "normal" price and not the super-cheap price, yeah?
