I havent seen a "rare" amiga get more than £500, including the Amiga Nyx that Haynie tried (and failed) to sell on ebay so I think five figures is a bit high but it would be interesting to see! ( I paid four figures for my current A4KT setup with all the upgrades, £2K plus yet the CDTV CR was super cheap!)
That A1000 the kid in Washington bought of CL went for more than 1200 dollars on ebay.
EDIT: Of course, that is probably around GBP500
