I made the mistake of purchasing one of those Thai
units. Don't waste
your money. Flakey software, scattered documentation, zero support
(doesn't answer e-mails).
Me too. And I loved it. The software was strange, scattered
documentation, zero support, but I never need it either. I know how to
program an EPROM and it just worked for that (and PLDs and microcontrollers
too).
Cheap tool, cheap service. But in my case it worked.
