I like the Baradine Microburner because it supports all existing PICs (with
appropriate adapters), and although it is shipped with a !@#$ interactive
interface like the other ones, it is completely ascii terminal based and
can be simply controlled by command line using the FREEWARE BURN.ZIP which
you can pick up on Microchip's BBS, my BBS, or probably several ftp sites.
It can also be operated  from nearly any computer with a serial port!

I think it's a bit more than $200 US but well worth it in time and errors
saved through automated programming!
