Well my Willem programmer works very well and was cheap.  However, it's a
Parallel port version.  Their new ones are USB based with even more chip
support.  You can check out their site here... https://www.sivava.com/

Also, these things are all over ebay for a good price. :)

I think I asked this before on the list, but what is a good USB programmer
