RG = the regular ones, bolt on neck, tons of different options regarding other stuff (theres more almost 16 models in their current lineup of RGs)
the RG1570 and up are Ibanez Prestige

RGA = carved top, fixed bridge (and I believe they belong under the Prestige line as well)

RGT = neck through (neck is one peices that runs to the end of the body with "wings" that make the body shape glued onto the sides. Great sustain, a kind of duller tone, really good upper fret access)
