I am just a customer, but my market research had only 1 "strong buy"
while big german vendors offer standard equipment at 200+ EUR this guy sells complete burners (PCB but no cable, power via USB) at 90 EURO, DIYT kits at 45 € which is really with hardly much of a margin

I have the Willem programmer v4.0 - I've ordered blank PCB only, bought all the components here and assembled. It works but has some design problems - the voltage selection is weird and the LPC/FWH access is horribly slow. There will be some support in UniFlash for it.
