Well that Andy's Auto Sports place that I linked before has a bunch of cheaper ones, I was just being a bit of a smart a$$.. not only that I have always wondered what other people thought about those two expensive knobs. I don't even know what I would do with a knob like that, it seems huge.

I like the momo one though, its good quality for a good price
There are cheaper ones out there, but they deteriorate quicker because your hand will be on it a lot. I learned that from changing knobs in my old truck I had.
