I use the Baradine Microburner for all PIC programming. It is relatively 
inexpensive (a few hundres $CDN) and it uses a standard ASCII interface so 
it will work with any computer.

I have also written a command-line interface which is available on the 
microchip BBS (3rdparty file area) and a few ftp sites as BURN.ZIP.

Adapters are available for all *EXISTING* PICs (16c64 is comming), I have 
them all, It works much better than PICSTART (I have one of them) and 
Promaster (have one of those too).
