I had picked up a set of a different brand with the same specs for about $50/pc but it seems that prices have increased everywhere since then. Ratings are good on that model though. So long as the 15" steelies you're getting are 4x108" PCD, 63.4mm center bore and 40-48mm offset, you shouldn't have trouble.
I'll be selling the set of ~2400mi steelies and 185/60R15 Nokian Hakka R2 tires I have soon, but since you're not in Michigan that probably doesn't help you.
