I just recently got a used Caparison Apple Horn (Aurora), and once I get some little things fixed on it, this guitar will be god. Awesome neck, decent pickups, and very comfortable to play. Guitar sounds awseome, I paid less than $1000USD for it. It is in "player" condition, but not hacked. I'm thinking this guitar may make my Ibanez's collect dust. I've got 4 other RGs, all in different pickup configurations, and ALL of them are wonderful instruments.
Unless you're looking for a neck through, I see no need to visit the prestige line, to be honest. As for trems, I really don't care for the newer Ibanez Edge Pro. There are some issues with the saddles not being pressed in straight, and I'm quite fond of not fixing something that isn't broken. NOTHING beats the original Edge & Lo-Pro trems, IMO. Caparison's come with Schaller trems, and are pretty much like your typical Floyd Rose trem. They seem to be rock solid, although I prefer the pop in Ibanez bars versus something that has to bolted down.
