They were sold direct from Gibson on the musicyo.com web store. I believe they were between $250-$350 (I can't remember which). I wanted one really bad. Yours looks like a re-wrap and seems to be missing the hi-hat stand. They were available in metallic silver, nitron yellow, and one other color (metallic blue, maybe?). I believe they have 4-ply mahogony shells. Nothing fancy but cool. I always regretted not getting a set.
I bought a lot of stuff from that website. Great deals on cheapo "made in china" stuff. Some of it was good. Some not. They always sent extra stuff too. I remember buying a Slingerland maple artist snare drum (which I still have) and they shipped a set of cymbals with it. They never charged me and didn't want them back. I sent them back anyway as I had no use for them. I got 2 complete sets (throne, bass pedal, hi-hat, boom stands) of heavy-duty Slingerland Magnamax hardware for $150 each. Logo heads, t-shirts, etc. I miss MusicYo.com.
