They're outstanding guitars, I'd sooner part with £400-500 on a Fernandes or Burny rather than dump more money in Gibson's useless pockets.
THe majority of the companies that were part of the 80's lawsuits by Gibson and Fender are damn fine copies, hence why they took legal action. They were no longer making cheap Les Paul/SG/Strat/Tele copies... they were making cheaper, high quality replicas of top-end guitars... look at the number of Les Paul Customs from that time and I'd bet if you gave two to a guitar player and blanked off the headstock, you'd be hard-pushed to tell the difference.
Take a £200-300 cheap Tokai, replace the pickups (essential) and maybe even some of the hardware (tuners, bridge, tailpiece) and you're still talking less money than an asbolute bottom-end Gibbo Les Paul Studio only you get ten times the instrument.
The key for me is value for money... you buy a cheaper replica, and you definately get more than your moneys worth. A modern Gibson is worth about half what the tag says to me.
