Ah, an A3000T! How I'd love to get my hands on one of those... But not at that price :-(
Ebay is indeed pretty wicked sometimes, both sellers and buyers. In Holland, there are a few guys who are selling stuff at pretty high Buy It Now prizes, yet somehow they seem to sell quite some stuff, especially to Australians. There must be some serious lack in Amiga hardware there (and a serious overflow of money...)
Currently there are a P-IV for 325 Euro (starting bid 300), a 4000/040 for 400 Euro, and a BPPC (160 Mhz) for 425 Euro.
Madness, if you ask me. And they also raid the local market (Dutch ad websites) from the nice Amiga stuff, only to make profit...
