well I'm pretty much still a newbie so I couldn't tell you much about guitars than what you already know. but I'll just say that I own an Ibanez, and I love the neck also! but I hate the tremolo. pretty much the same case you've got, cept my trem didn't pull out until I owned the guitar for a few months so I didn't have the pleasure of just returning it. from what I hear the neck of a gibson sg is very similar to the neck of an ibanez. and the sg has a set bridge. cheapest one you can find probably be about $650 though.
