I had an Austin PRS copy. It was a decent enough guitar, but it was made out of alder instead of mahogany. If that matters, find out before you get the SG copy.
Not sure, but aren't they pretty low budget, like entry level? I'd much rather have an Epi G-400. I can count on a certain level of quality in materials and workmanship. You can get used Epi G-400's for good prices.
