Hiya Dave
Not sure what eeproms are in your sets there, but you can obtain a number of programmers quite reasonably off ebay.
The handheld ones, by which I'm guessing you mean the DataMan S4 (or similar), tend to command high prices even now.
The one I obtained from ebay is called "Topwin". They come in various guises and with various capabilities. There are some bare PCB programmers, but for a few extra pennies you obtain a really smart looking one with excellent specs.
My particular one is a "Topwin TOP2004", which came complete with cable, software, extractor tool, and a number of adapter boards. The software will run on Win98, Win ME, Win 2000, Win XP. The unit connects via a USB port on your PC.
Here's a link to one currently on ebay:
USB Universal EPROM EEPROM FLASH GAL Programmer AVR PIC
There are a number of others on there, the above is just one example. If you take a look at the list of devices the unit can program it's enormous! The units come direct from China, and mine arrived within three days of ordering.
Hope this info helps you out Dave!
