^ like he said, year? trim (LE or XLE)? new or used?
if you want new, forget about cheap... most after market places don't carry that trim. your only option is a dealership or online dealership for a brand new one, and that will run you anywhere from $150 - 200 if not more.
if you want used, go to junkyards or ebay. you may even get lucky on the For Sale section on this forum. in fact, if your car is an 02 - 06...i have two for sale. I have the black/charcoal stock one for my LE, and a grayish green one with chrome accents for an XLE. pictures located in link below. PM me if you're interested.
