I see absolute no problem to find universal programmer manufacturers on the web.

But I assume such an universal programmer would cost a little:
E.g. 10,000$ for the basic module and 1,000$ for every adaptor for all the different cases of the different devices, which you want to programm.

The cheaper way should always be to focus only on some devices and then buy cheap special programmers from the manufacturers, e.g. the Atmel STK500 for most of its AVRs.
