Ibanez RG 1550M Prestige
Ibanez RG 1570 Prestige
Also for under 600 bucks check out the Sterling JP50(musiciansfriend). Buy this and then drop in whatever pickups you prefer with the money you saved. My friend has this guitar and he just raves about the quality. I have the Ibanez RG 1550M that I mentioned and it rocks!
