I have a Hamer Archtop SAT II... nice guitar. Modelled after an LP double-cut, except with a gentle arch to it. Most of the guys I know tend to slam Hamers as being copycat guitar makers but I think they have very good build quality... the more I play mine the more I appreciate it. Good balance and heft and it resonates very nicely.
I don't know about the XT line... in my experience the cheaper lines aren't necessarily worse guitars - they're simply Asian made and sometimes, but not always, have less quality in the way of pickups and hardware. I have a few Korean-made guitars that are really great players... I'm guessing the XT line is made in Korea, Indonesia or China. Bit of a crap shoot as to what country tends to make better instruments. Hopefully someone who actually owns an XT will respond.
