I just finished Planescape: Torment and was planning to start Baldur's Gate next, and was looking for some mods.  
 
I've started it a couple times, but never gotten more than a few hours in (start of chapter 2, I think), in case that changes suggestions.
 
I found a site called Sorcerers, that has some mods listed.   Anyone know of other BG mods sites, or specific mods they think of as essential?

Now check out my blog entry for Baldur's Gate mods.

" @Garden_Ninja: Hey bud, check out my blog entry about Baldur's Gate II mods.  It has links to sites that focus on Infinity Engine games and their mods. "
