Well, at the expense of beating a horse to death, Gibson Les Pauls for me. There are so many guitars that can do what a Gibson Les Paul does at a fraction of the price.
Another that comes to mind is the PRS tremolo, which will run you $400-$500. It's only a guitar part, not a whole guitar. What, are they gold plated or something. C'mon.
