ive got a 1999 rg450dx, which ive had from brand new, and its got a wizard 2 neck, lo-trs trem, and infinity pickups, and its still my main guitar - its what im used to, its what i essentially learned to play on, and its what ive played and gigged with for almost 15years! its not a prestige, or a j custom, or a jem, or even a premium - it is to all intents and purposes the same as the current rg350s (which come in all kinds of eye popping colours!). ive also heard several good reviews on here abt the 350s bang for buck!!
now dont get me wrong, the neck is thicker than the wizard, the trem doesnt even begin to compare to the edge, and the pickups are a bit flat sounding compared to the ibz/dimarzio ones ive got, and even the v7/v8 ones too, but that doesnt stop it being a pretty decent guitar, and it kinds feels like home in some ways.
i would say if u can find something in the 3xx-4xx series for not a lot of money, then get it, if you dont like it, you can always sell it on again for pretty much the same as you paid for it! and if you do - BONUS!
