On the west coast (at least) there is a chain of discount leather stores called Leather Works. I bought a black patchwork leather apron from them years ago and it has served me well in the darkroom since then. It is a smooth enough finish that chemical splashes stay on the surface and is easy to wipe off with a damp cloth. It has side and front pockets for holding accessories and the side pockets are lightproof, so I can keep my cell phone in one and not worry about fogging anything if it rings at a critical time.
Best of all, I think I paid 10 bucks for it. Last time I was in a store (last summer) they still had them in stock.
