You can get new wheels for around $100 a piece and even cheaper if you go steel, all perfectly adequate.
The problem you may encounter with stock wheels is that they aren't as wide, or have as much backspacing as pretty much any of the aftermarket ones, which is why they get replaced so often.
I'm with @Lxxtsy. get some of the peel off car paint (dupli-coat or rustoleum's peel coat) and use that for awhile. I did that for several months before getting new wheels. The stuff is pretty durable and forgiving to apply.
