I am pretty set on wanting an Ibanez Prestige RG series guitar, but there's like 10 different ones in the Ibanez Prestige RG line. Is there any severe difference to their quality aside from some being a 7 string, paint job, or H-S-H or just H-H setups, etc? I was going to get a RG1570 because everyone speaks so highly of it. But what is wrong with the others?

*note: Throw price range out the window for now.
