That's an excellent point about money, and as I'm playing more with the free tools available I'm liking them more and more. At least to start with, I'm probably going to go with one of them.

FanHistory, from what I've seen, documents the history of fandom primarily and only briefly the canon of those fandoms, so I wouldn't think there'd be too much overlap there (although I should probably at least consider the name thing - bandom vs. ebandom vs. Six Degrees of Pete Wentz vs. whatever else we are.)
