Ken,
I did a quick Google and found several on ebay, listed as new for 300 or less. You didn't say if this was a single or dual DIN opening, but I expect it is a dual. Any good radio shop will be able to help you with adapter kits so that wiring is plug and play between units. I recently pulled the dead radio out of my Jeep and replaced it with an aftermarket and the shop that sold me the radio supplied adapters for everything so that even my factory steering controls worked on the radio.
