Last year when the new Gibson Jimmy Page signature doubleneck came out I had some extra money in the bank and thought of buying one as an investment. Turns out I couldn't get to the store opening weekend and decided against it when the guitars were still available at original price weeks later. They remain in stock items at GC. Two weeks from now the new Jimmy Page signature les paul is being released. It's being promoted heavily by GC. There was a thread here last week (which I can no longer find) in which several people inidicated they were or had already made purchases for collection. One person went as far as predicting they'd be $25K on ebay shortly after being offered for sale. So I'm wondering, when are these kind of instruments truly collectible and when aren't they? Or why some and not others?
