Go for the best electrical design.

I'm an 'open source no-profit' type guy in it for the fun. Occasionally
profit makes it all come together, like the SDR-1000 ---- We have an actual
device we can use, and a group, which through selfless contributions makes
it better! Not a bad model. To my way of 'freethink' is as soon as I make it
a product for profit, I'm obligated to things I DON'T like! (smil)

Let's keep truckin'!


Thanks
Eric

It's going to be mostly SMT. I'll put a prototype together, but a board like

this really has to be assembled by specialists. I was using 0805 parts, as 
I've got plenty, but it might be better to go for 0603, for the FPGA supply 
pins. Xilinx recommends 0402 for their FPGAs, but those applications 
typically run much faster.
