Can the idea of the Ibanez GRG. With your budget go for something better, just remember, the low end of any company will feel low end no matter how much it costs, so forget Jacksons as well, the entry level JS series are around 400-600 if I'm not wrong. If you're into fat fat fat BUT potentially muddy tone, get the Les Paul, from what I can see, your choice of music will not require you to shred like a madman, the Les Paul is not exactly shreddable but it WILL suit your tone for your music.
My suggestions?
ESP LTD, they pretty much make among the best guitars in that price bracket
Cort, If brand isn't a problem for you, they've got excellent guitars for the price.
Ibanez, anything, just stay away from the GiO range, their pretty darn value for money too.
Specific guitars :
Ibanez S320, I forgot the price but I think it shouldnt be off budget.
ESP LTD EX-250, definitely within budget, give davis a call, should be sub 600.
