get a used processor here and a multi channel amp, and spend the rest on good new matching line of speakers. Others may differ but I think used for youe source is a great idea...buying all the same manufactures speakers will give you the best image of sound possible.
If you already have a good 2 channel rig in a dedicated room maybe look into Definitive Technology for theater speakers...good price and performance for movie sound.
