Decent and cheap can't go together in the same sentence when talking about car parts.
What is your budget? Try looking around ebay or even in our classifieds secions. There is also a FS/WTB thread in the RB forum. Have a look in there, and you might be able to find what you are looking for.
EDIT: Here's one I found seaching Up-Garage.
