Nah, man, don't listen to these Ibanez detractors, I own three and they are all superb axes.
My baby is my JPM004, that's the John Petrucci model in the Camo colours, and it plays like a dream. Nice, well rounded neck, very quick fretboard, sick pups and it just looks fucking badass. Oh, and the most important thing about the top end Ibanez's is that they have the best floyd rose trems in the world. I don't care what anyone says about the old fashioned originals, Ibanez Lowpro or the new adge are just simply the best, aesthetically and useably.
Anyway, if you want grim Ibanez, and it seems that you are quite determined to have something custom, you should try out some of the prestige Ibanez's, and then get a custom paint job. It will set you back a few quid but if it's what you really want...
For me, the linchpin metal guitars are Ibanez and Jackson. That's not to say that other brands are no good, but top end models from these manufacturers will do you no hard at all. There are shitloads of really good independant custom shops out there, too, so check out a few.
I personall love the work that this guy does:
