Epiphone makes good guitars. I played on an SG once, the only fault i found was the balance, but then again, that is in the SG's design, Gibson or Epiphone. BTW: Gibson Thunderbird is the most awkwardly built guitar ever. I wish I had a Mosrite. I have no idea how they're like to play, but they look so cool!!
(I want to have at least one guitar were I can say "It sounds crap, but maaaan, just LOOK at it!". YAY!
