I'm a little late to this party but I thought I'd chime in anyway in case anybody is still paying attention to this thread.
I've built a few cigar box guitars and still put one together from time to time. I've got this one hanging in my living room. It's got a piezo mike inside so I can plug it into an amp and really make it wail. Not that I really know how to play a lick but it's fun anyway.
The best source for kits and parts from the most basic to pretty sophisticated - for a cigar box that's a bit of an oxymoron - is CB Gitty in New Hampshire. They are really good folks that work hard to promote the hobby. I don't have the link handy but any search engine will bring them right up.
