Is it just me, or...

Is it way hard to get a model of anything into TGE... Im a programmer type, and while code just flows from my brain, modeling seems too complex... i mean, i can make basic shapes, which is fine. i can export them and get them in the game. untextured as it is, but i can stretch my imagination. my question is, does anyone have a difinitive walk-through or tutorial for any of the folowing:

skinning a, say, weapon model.
or, the like. Any really good tut. Or downloadable models i can use instead of that silly guy in the tech demo... im not looking so much for something to distribute, just something for my tech demo.

Anything is appreciated.
