I'm the one who got this A3000, by the way. (...in fact, I'm using it to post this)
$400 was a bit higher than I wanted, but I didn't have to worry about shipping or customs - it was local. I also really wanted that 18Mb RAM so I wouldn't have to search for rare zip chips. It's in great condition and works perfectly.
Another thing: I used my A500 to bid on it... and won in the last 3 seconds. Actually, every eBay bid I've ever made was using my A500. My best timing ever was bidding at the exact second bidding ended. (bid time and end time were identical!)
