Re: Is it worth replacing a bridge?
+1, I'd try getting it properly adjusted first. Pick up a copy of Dan Erlewine's "How to make your Electric Guitar Play Great', there's a great section on Strat trem adjustment. I always blocked mine off untill I read this, now I love a Strat trem. It worked on my nephew's Affinity Strat, too. Both have a nice loose feel with 2 springs, and both stay in tune fairly well. No Floyd dives, but that's what Floyds are for.
