Thanks for the link, some people might find it useful, but I don't think I would really recommend a kit like that. If nothing else, I think 3mm LEDs are too large, I used 1.8mm. But the main challenge isn't soldering, it was drilling all the holes and running all the wires.
I dunno, I know how to solder, did so, but if you don't have a soldering iron you you can always twist and shrink wrap.
