I think I spent more on minis, pirates of the spanish main, and boardgames than I did on RPG books in 2004, which is a first.
I don't anticipate spending alot this year, either:
C&C stuff, some Conan d20 supps, Thieve's World, and some pdfs from DTRPG now that they ditched DRM (CSIO for sure, and probably some other Necro products.)
Probably right around $220 or so for the year would be my guess.
