I've got a an AL3100 and a Septor 727, and they're both excellent. The finish is flawless, the frets are good, and the feel just screams quality in a way epiphones never can. The've both got ebony fretboards (the one on the Septor is astonishing, it's like glass), and the AL has real MOP inlays. The Septor is a 5 piece neck through with mahogany wings, a flamed maple top and an ebony board, and it cost me £380 shipped from the states with taxes. The AL cost the same with a hardshell case!
The only thing I don't like with the AL is the pickups, but that's a taste rather than quality issue (they're a bit too vintage for me), and I'm mid solder job as we speak :)
Is the 3100 better than an epiphone? yes. Is it as good as a "good" gibson? No. Is it better than a "bad" gibson? Probably. The bottom line is that you won't find such a good value for money guitar anywhere else. If it weren't for the exchange rate at the minute I'd probably have bought another two by now.
