Early/mid 90s Jackson Professional, the Japanese built ones. I have a 92ish Fusion and it's bulletproof. Licensed FR is rock solid, only needed a pickup swap (I stuck a DIMarzio in it in 93, not BKPed yet).
Personally I don't like the 6 string RGs, or rather the necks - the Jackson is a bit fatter & flatter. YMMV, obviously! :)
Note: I've seen a couple of Concept series on evilbay. These are fantastic too.
