I picked up a MIM standard Strat a few weeks ago, and I've heard how many say to replace the pups for best results. I was browsing my local GC yesterday, and happened to find this set on clearance for $129.

I really have no experience with other pickups, or what the sound difference would be. I'm just starting, but I am looking to play Blues, Rock, Classic Rock...nothing really too Metal. I don't even have the slightest idea on how to replace parts either, so I would guess I would have to ask my local guitar shop what the charge would be to put something like this in, if I were to do something like this.

Just looking for some input and opinions, and any feedback is greatly appreciated.
