Re: Ibanez RG 7420 - Neck question
Seems like a good price. If it's in good playing shape (or can be brought into it with a few tweaks and maybe a fret polish) then that's absolutely a guitar you'll get your money's worth on, plus some.
Sevens are fun - I made the switch in 2000 or so, and while I still play both a seven string is my primary instrument. The extra range, only five extra notes on paper, actually opens up quite a lot of potential on the neck.
