Not sure if this is in the right place...

One of the few things I hate about my car is the steering wheel... it's too thin and the 4-spoke design annoys me, and I can live with it, but I hate the material it's made of. Anyways, are there any limitations to steering wheels I can use? I want something thicker, preferably leather, and I want to retain my airbag, and I've found that my last preference rules out most aftermarket wheels. Also, I'd like to keep my wallet at a healthy weight. Any help is appreciated, I've just never changed one out, so I don't really know.
