I live in Warren, which isn't too far from your location. I have a set of chromed 16x8 rims that you can pick up for a mere $50. They were used during the winter so the chrome is pitted and peeling, but your requirement was that they only be straight.
I think that you could get them re-chromed or even sand blasted and powder coated for a reasonable price. In any case, I'm not sure what the cost would be to restore them...but that's why the decent price for all 4.
The attached picture are the style, but not the actual rim. I included it just for reference.
If you are interested in picking up this set, please let me know.
