Fish-N-Chips

I have none of the tool's required to do that, and I don't know if I trust myself with something that intricate. I'd be willing to try it for one club though.

I like my clubs, but I realize that getting newer clubs could help my game a little bit. Any thoughts on some decent sets I could look for?

I picked up golf about a year ago and I have been swinging a set of 2004 Callaway Big Bertha Irons. I really like them, but the graphite shafts on them are beginning to crack. The 5 iron and pitching wedge are already unusable and the 7 iron is close to it. I'm just looking for some suggestions on what I should do. I have about $150-$200 to spend, and I'm assuming I could get about 70 or 80 for my old sticks. Thanks in advance.
