I got one for my 84 off ebay. Keep checking, you're likely to eventually find a good one at a good price. Chevy changed the woodgrain style I think it was between 82 and 83, so make sure you get the one you want.
if you have some minor woodworking skills, how 'bout this? go to your area woodworking store and get some burl veneer, it's very thin and easy to form with a steam iron, it will attach with contact cement - put 2 or 3 coats of a GOOD poly (no lacquer or shellac) finish on it (300-400 grit between coats). let it cure for a week (a whole week) then wax it. it'll look awesome (but you'll then want to do it to each panel!)
