I've been looking for a lil while and I can't seem to find one, anyone know of one?

There's the http://www.gamesas.com/topic/1081671-list-of-modders-resources/, or were you looking for something particular?

Wow I am blind, thanks.

However, I think that list should be unpinned because it isn't regularly updated. Browse the list, but you can also browse Nexus category and tags.

Is there one that is regularly updated? I've looked through nexus, I'm mostly looking for some unique tilesets and buildings.

That's probably the most up to date one you'll find. Last updated in October, that's not that far back.
The last page, 4th post down, then scroll scroll scroll, you'll find the Tilesets and Architecture list. It's fairly extensive.

(also check out washington's My resources link in his sig, I know he's done some nice ones.)
