I wouldn't pay 15K for the whole 59 Les Paul unless I was filthy rich...I've played a few 50s paulas...they did sound very,very nice and were built like a tank...but they aren't THAT good! .The whole collectors thing is just outta control, IMO.
The DUMBEST thing (IMO of course) I see these days are the "aged" guitars. Beat up...paint chipped off, nicks and dings..etc etc...Buy a 3K instrument then pay someone else to beat it up a bit...
Now, I can understand wanting say a authentic replica of a 61 strat or a 58 Les Paul ( I want one)....because of the design differences compared to instruments of today..and Fender/Gibson can accomodate you in their custom shops. But why the heck would you have the guitar 'aged"??? Who are you fooling? People who actually give a rats @$$ about vintage guitars will spot it's an Aged model, and of course the owner knows it's not a "real" 58/61, etc.
It's like the kids who post a big sign in the front windshield of their that says *NISSAN* or *HONDA* or whatever....anyone who gives a crap already knows what kind of car it is, and the rest of world thinks you look lke an idiot
