I liked the Trevor James I had, it was a Horn Revolution II alto, and I used a Selmer mpc on it. It only had one minor problem, the Bb on the l.h. pinky was a bit of a stretch for my smallish hands, and when pushed it did get a bit thin in the upper register... two minor problems... but the upper register thin-ness could have been the mpc I suppose, but then I was very inexperienced when I had it.
All things considered, though, I'd say the James is a good choice.
