Bought a 4000T off him. It was fine. Expensive, but ok. As far as a yellowed keyboard, it's hard to expect anything that old not to be a bit yellowed. Plastic degrades over time anyway. I think the days of expecting "perfect" condition Amiga hardware that has not been manufactured for close to 10 years is a bit unreasonable... If it works well and has no major scars, then I would define it as being in excellent condition. My 2 cents.
