I really can recommend sp12 for this - 3 Cs, 4 Rs and a crystal on the
parallel port. It works for me quite well, without external power supply.

Check http://www.xs4all.nl/~sbolt/e-spider_prog.html

Of course, as with every serial programmer, you won't be able to set certain
fuse bits on certain AVRs, but isn't the STK500 a serial programmer too? At
least the STK300 was...
