You won't see any user-made modules for ToEE, unfortunately -- the art is all hand-rendered, not tile-based like NWN. So unless there's a user out there with his own art department to to do all the backgrounds, the tools aren't there to do custom mods, even though the engine is easy to program.
I've liked ToEE a lot, even with the bugs -- I've yet to experience a game-stopping bug, and the patch has fixed most of the minor bugs I would otehrwise complain about. It's the most true-to-D&D rules CRPG out there, and the combat engine is great. It still has the flaw of not as much character interaction/RP (compared to BG2, say), but I'd put that element on par with the Icewind Dale series.
I actually went back to try a couple of user-made mods in NWN recently, and had to quit after an hour -- the repetitive sameness of the tiled background was boring, and the "click on target, apply no tactics" style of combat was incredibly frustrating after ToEE's combat engine -- but note that I only play single-player games, which is hardly NWN's strength.
Edit: The official demo (which is all dungeon-crawl action through the moathouse) is out, download and give it a try!
