A common complaint about Epis is 'fret buzz' or 'high action' (to avoid 'fret buzz'). My experience of them (I own three, acoustic, archtop and solid) is that they come out of the factories with the truss rods overtight and no string relief. Loosen them up a little and they are great.

I got a second-hand LP100 dirt cheap a few months ago because the owner 'didn't get on with it' (he didn't want to admit that the strings buzzed). A bargain, and a really nice player with a little TLC.

A major cost-saver for manufacturers of 'economy' names is minimal set-up/adjustment before the instruments leave the factory. Get a cheap guitar and a good book, and teach yourself some guitar techie stuff.
