Just want to throw in my 2 cents worth... ALL OLD AMIGA HARDWARE is ai-is and you should assume issues and bid accordingly. When I sold some of my Amiga Hardware on ebay - I showed pics it working - but gave no guarantee/AS-IS buyer must insure. Old computer equipment - especially bulky Amiga hardware - most likely must ship US email to be affordable so you have to accept its a always at risk. Decide how much you want to risk and bid accordingly.
If the seller doesn't want to test and show working - then just accept it may be broke and don't bid high. Ebay is the ultimate free market - the demand sets the price. I'd love to get a MegaMidgetRacer for my trusty old A500 - but after a 68030-25 for my A2000, I just keep A500 for playing those pesky games that don't like acceleration.
Also, kinda on but off topic too - as time goes by Amiga hardware will become rarer and more expensive as long as people care about it. Just look at classic Atari consoles like the 7800. They where great ebay items for a while - but since they don't work on modern Digitial TVs, the demand is going away and the one I sold with games for over $100 a few years back goes for like $25.
That is something else people need to think about - a lot of our vintage stuff will eventually not work - especially if you hook them to TV, etc cause new TV's don't support the old NTSC analog. If you don't have a way to hook your Amiga to a monitor - you better be looking at a way to when that old analog tv dies.
