Re: Giving up on current Ibanez?
If you're looking outside of Ibanez - take a long hard look at Carvin. The DC models are neck thru and shorter scale, but the C66 and Bolt+ are bolt-on and 25.5" scale.
If you're looking for the fancier of the two, the C66 is your choice, as it comes with a flame-maple top. The Bolt+ is the more economical choice as it comes with a standard alder body (but you can always option up).
The heel on the Carvin bolt-on guitars kinda stinks, but it isn't very prohibitive to higher fret playing.
If you hate the locking nut, Carvin give you the option of getting your Floyd with locking tuners instead of the locking nut. You can also get a Wilkinson if you're "over" the whole Floyd thing. They also have options for string-thru bridges or a fixed bridge.
I spec'd out a Bolt+ with a Floyd and added a mahogany body, maple board, mahogany veneer for the reverse headstock, and black hardware and it came out to $898.00 with the case.
If you're used to Ibanez, you may want to spring for the flatter 14" radius, as Carvin's standard is 12".
Go to Carvin.com and price one out. They're great guitars, I own two of them (an AC 175 and a DC135 with no middle p-up, so it's H-S - a custom option).
