Pickups are not that hard to replace if you know what you are doing. For the jazz bass though, I probably wouldn't switch them out if you have the noiseless pickups in. I've played one and they sound good to me. I know with my Ibanez SR506 i'm going to get EMG pickups put in as soon as I get another bass just because I want that EMG sound. You should keep shopping around for basses that fit in you price range, I'm sure you will find something. By the way, what price range are you looking at?
