I keep forgetting about Blender.
It's GUI is amazing, since you can set up the screens however you like. I never did get into the habit of modeling anything that looked realistic, but maybe I could try making some models for TF2 =O!
Also, this is the first tutorial I used:
http://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro
That one helps you learn the GUI while making simple objects (I skipped straight to meshes in Unit 2, but it's probably helpful to read the last bolded section in Unit 1)
Texturing in Blender is more of a problem, as you've got to figure out your normals and make sure they're pointed the right way. Can't remember where I learned how to do this, though...It's possible it's part of the wikibook, though.
ALSO FYI: The Wikibook is probably not complete. I just kept working until they ran out of instructions on 5 consecutive pages.
EDIT: There's a smilie in the URL and it still works perfectly. Hehehe.
