Tony,
? I tinned some of my first home made pcb's but never again. And the boards I ordered are of the ENIG variety. No rocket science comes out of my hobby. :)

Unless you're a manufacturer, RoHS (or whatever your local flavour is) isn't
a problem.
Space vehicles are exempt from these regulations, I guess they figure not
many of them are going to wind up in a landfill. For the tin whiskers, the
problem wasn't lead-free solder, it's the tin plating on the copper tracks,
something even hobbyists do. I think they nickel plate stuff like
spacecraft PCBs now.
Dunno if there is a chemical solution to do nickel plating on copper like
you do with tin, but electroplating nickel is really easy.
