i've played on yamaha, kanstul, dynasty, and crappy student model kings. i can tell you if you band director goes for king it had #### well better be their ultimate marching brass and nothing else. i like kanstul, good tone quality, good intonation, especially with baris and all not tuning. dynasy, not much to say, not bad, not great, decent, i played one all last summer. the only real beef i had with it was that bracing on the third valve slide. i havent had the chance to play on the new ones yet. now yamaha. i dont know what it is about them, i just dont like the horn. i have nothing to back that up with so i'll leave it at that.
