The next EPROM programmer I buy will be a Needham's Electronics programmer,
which digikey sells for 139.94.  It does flash, handles HEX or S-Files, and
is a unit made in America that you can get support for.  Handles up to
32 pin devices, and I think it has an option for 40 pin parts.  It supports
almost any chip you'd be likely to use, and 'I think' you can get upgraded
software from the company if you need it for new parts.

Our company has an Intel Flash Evaluation Kit, which includes a version of this
programmer (rigged to only program Intel devices :(  ), which has worked
very well for us except for the Intel imposed brain deadness.

We also have a Gang programmer made by Needhams (8 chips, $750) that gets
quite a bit of use on our production floor.  It flipped out once and Needhams
sent us a replacement Next day air, before they got the dead unit returned
to them.

I own a MCT (Modular Circuit Technolgys) programmer that I bought from JDR.
I would not recommend it to anyone, and you cannot get support for new chip
versions with it.

Also, I would recommend using flash over EPROM any day of the week.  It is
a lot more convenient for very little more price.  Even if you ship a finished
product with EPROM, I would still use flash for development.
AMD flash is self timed and inexpensive, they also have 5v programming voltage
parts.   MUCH easier to program than stuff without self timers, and MUCH more
reliable.
