I have two Universal USB device programmers, both bought from China, one through eBay and one through AliExpress. I started out with a TOP853 and subsequently upgraded to a TL866A. More details on these programmers can be found on their own pages.

Parallel Port Programmer

A Needham EMP-20, bought from eBay US to program some legacy devices that my USB programmers would not touch. More details on its own page.
