If you're in the market for an EPROM programmer,
take a look at some of 
the
  stuff Elnec (
www.elnec.com) are offering. I picked up
a Preprom-02ALV
 EPROM/Flash programmer a few years back for ?160. IIRC the Preprom has 
been
  discontinued, but there is a replacement for it at
around the same price. 
    This is too expensive if you consider the willem eprom programmer
(
www.willem.org) which has all the schematics on the net and programs almost
everything you can think of.
