that's really the only thing that I could find that might work... the only other option that I can think of, is to go to ibanez.com and click on "parts" then find your guitar and copy the part number for the neck, then go back, and click on support instead of parts, and enter in the part number. now, usually for me it comes up with 0 results... but you might get lucky, then you should have a price on a new neck.
