I have an M2L Electronics EZ-EP programmer.  It works great, and can
even auto-detect some ROM chips so you don't have to pick them out of
the menu.  It is a parallel port device and I use it on my PC and my
laptop.  Works with most EPROMs, EEPROMs, and Flash ROM.
They are $170 from http://www.m2l.com.
I have no affiliation with the company, but the owner is a really nice
guy.  Around 3 or 4 years ago as a poor college student, I wanted a
parallel port programmer that could do Flash ROM.  Most were out of my
price range.  I wrote to M2L asking for more info about their EZ-EP, and
at the end of the message I only half jokingly asked if they offered any
student discounts or anything.  He replied that he would sell me an
early prototype for $80 if I were interested, only difference being the
PCB layout wasn't as clean (a few wire jumpers) and no power LED.  I
bought it, and it has worked perfectly ever since.  In the next few
months, I burned many flash chips, and came across some new ones that
the programmer didn't support.  Again I wrote to M2L, asking the owner
if he could write in support for the new flash chips.  He said to just
email a datasheet, and he'd start working on it.  So I located and dl'ed
the .pdf datasheets and emailed them to him.  A few weeks later, a new
version of the software came out with support for the new chips.  I
think in the end I asked him if he could implement support for at least
3 new flash chips, and if I remember correctly, they are all supported
in the latest software.
Definitely a respectable company that I highly recommend.  It may be
more programmer than necessary, but if you want to be replacing 27C256's
with 29C256 flash ROMs like I do, then it may just come in very handy. 
Anyway, that's my 2 cents.
