I'd probably go with option B. I have a basic Radio Shack soldering iron, and while I'm not afraid to use it, neither do I have a lot of experience beyond soldering wires for installing car stereos, etc. Plus it would leave me with enough to do to have a little fun and learn a bit.

Since I don't have an immediate need, and I'm on a very limited budget, I'd probably just buy your PCB and the BetzTechnik board right away and then wait on the rest until I have an actual use case.
