Right now I have a set of Spalding Eagles I got from my uncle, but they're pretty worn out; the clubheads are all rusting, and there's no more life left in the grips. Besides, I'm missing the 7 iron, and don't have any wedges. So, I'm looking for a new set of irons, 3 or 4-PW. I want cavity back clubs, and want something that is similar to the clubs I have right now, because I actually kinda like them. Only problem is I only have about $300 to spend.

Any suggestions?
