I will be one of those hard time first builders, so expect a million questions once I get everything in one place. I'm not worried at all about my Pekochu mod since I can tinker and fiddle with the best of them, but soldering little electronics... yikes. I will almost definitely need to buy a new soldering iron. (I think mine was a radio shack special handed down to me from someone else who soldered once every decade.)
I would get some old electronic device, pull out the circuit board, and practice on that. My early soldering was pretty crap, but it has improved dramatically. There's some great soldering tutorial videos online, very useful to accelerate learning.
