$285 is way to much money for an A2000 in Sweden. The seller is a dreamer.
Remember that Amiga was actually fairly popular here, it is not a rare computer. I got the impression mot people do not want the A2000, it is a heavy and large computer. I am sure you can find one for 50 euro if you ask around (or for free).
For $285 you can get an A4000D.
