The high end RGs come with Dimarzios.

They do, but they're often the lower-end dimarzio models (which aren't all that much better than Ibanez pickups), either that or they're licensed copies. I'd rather get a low-end ibanez guitar, and get my favorite pickup combination in it. I use Kahler tremolos anyway, so I'm gonna have to spend a lot of time on custom work anyway, might as well get new pickups too.
