S4 Engine

I am looking for a 00 or 01 S4 engine for a project. If anyone can help by telling me where to look for one, or where they have seen one for sale, it would be greatly appreciated. I would also like to have the 6 spd tranny, driveshaft and rear diff and axels if possible.

any actual sites that sell salvaged engines and trannys?

Website would be cool, i'm trying to stay away from e-bay though. A salvage yard would be ideal, or a shop. I'll probobly need the engine, 6 spd tranny, driveshaft and rear diff w/ axle's to start out, then other parts as i go through with it.

..maybe try www.dadsauto.com
