I don't know why tompeter lists every vanilla ST\STE listed on eBay.
Prices these days seem to be very high. I saw a plain 520STFM in an antique shop, boxed with Discovery Pack wrapper for £90 untested.
I would be more interested in a MegaST\MegaSTE or Falcon but I know these are rare. It does no harm to list these things though.
Still got, still working: Atari 4Mb STe, 520STFM, 2.5Mb STF.
Hardware: Cumana CSA 354, Ultimate Ripper, Blitz Turbo, Synchro Express II (US and UK Versions).
