I'm no stranger to 7 strings, I've been wailing on brothers RG7321 for about a year now. Its nice, but I decided its time to get one of my own, I've been doing research based on these requirements-

Budget- £500 at the most
Preferably hardtail- won't use a trem
Thin neck

Theres others, but those are the most important. So, I came up with these-

Ibanez Apex 2

Mahogany Body
5-pcs Wizard II-7 neck (25.5" scale)
Rosewood Fretboard
24 Jumbo Frets
Tone Pros 7 Bridge with String through Body
2 DiMarzio PAF 7 Humbucker

Good specs but I'm not a fan of the colour and I'm pushing the budget a bit.

Schecter Demon 7

Basswood body
Maple neck (25.5" scale)
Rosewood fretboard
24 frets
Tune-O-Matic bridge with strings through body
2 Duncan-designed HB-105 active pickups

Its a good price and decent specs, but I'm afraid the neck may be a bit baseball bat-ish.

So, which one should I buy and why? If you have any other suggestions I'm more than glad to hear them.

Thanks guys

Ibanez no contest. Better woods, better hardware, and better craftsmanship (made in Japan vs korea).

Also, if you don't mind buying used look for an Ibanez RG 7621. Big Japanese brother of the 7321 you're playing.
