I'm happy to send you a kit of parts if you fancy building one, I find the SMD machine a bit easier though
I'll take a fully assembled board with USB
I could just imagine how pissed I'd be when I spend several hundred hours assembling it and it failed to work.
It would be worse than the time I typed in a several page of HEX code from RUN magazine and on completion it tuned out to be an April fools joke...
