memphis brand telecaster, anyone know anything?

i saw a telecaster guitar in a store window yeterday among some other vintage fender guitars. it was a black Memphis from the 70s and i'm told it "sounds really cool" but i didn't try it out. i like the store. it's $600. has a maple neck. i know Memphis is a brand that doesn't exist anymore. i was wondering if anyone knows anything about this brand and if $600 is too much for a vintage Memphis telecaster.
