I have a Schecter Diamond Series 7-string. I am quite partial to 7-string guitars. On the pro side, it's got a big neck and, with a black body, looks cool. The pickup sounds hot. Affordable, at 8,000 baht (around $250 USD).

On the con side, the big neck slows me down a little bit, and my fingers don't fly as fast as my Aria Mac-series 7-string, with a smaller neck. Also the oddly-protruding top horn has made it impossible thus far for me to find a suitable hardcase.

Overall though, I give the Schecter Diamond Series 7-string a thumbs up.
