The ESP LTD Viper 400 is an amazing guitar for the price, and seems to match your requirements pretty well. Second one down (or 3rd if you like active EMG's).

They are basically a cross between an LP, SG, and... I don't know. They have a set neck, play very fast, have great sustain and sound, built great, and they look awesome. Plus they can be had for well below $1500 (about $599).
