ive got the 170 and its gorgeous
ibanez make the best guitars in my opinion,
i think theyre incredibly easy to play and still produce an amaing sound
I had an RG370DX for almost a year. It's a good and very playable guitar, but the tremolo isn't too great. The guitar wouldn't really stay in tune when using the tremolo, so I blocked it by using some plastic. However, once i did this, the guitar stayed in tune no matter how hard you played or bent the strings.

Saying this, you might want to check out Ibanez's "fixed RG" line and save some money as well. Something like the 321mh or the new RGR321EX.
