I've done a little research,
First of all, these Gibsons are selling online for $850, not the thousands of dollars people have been saying about a lot of Gibsons.
Unfortunately, according to some threads I researched on the Les Paul forum, these 50s Tribute Studios are casualties from the Nashville floods. Gibson released this model, people went crazy for it because its such a cool platform at a reasonable price, but the floods came and closed the factory. They are just getting back to work in the Nashville facility now. A lucky few have actually gotten their guitars, but most are on backorder waiting to be built. And that cool goldtop? Well it sold out of its production run, so those are nearly impossible to get unless you have a low number on a waiting list at a Gibson retailer. Apparently other colors might still be available, but again, on backorder.
I guess these were intened as a limited production issue. Since it has generated so much buzz, there is talk of making it a regular production item, but thats just rumor at this point. It does make sense given Gibson's dire financial situation.
