There are those that would disagree with me on this answer, but I have played semi pro 30 years got a saxophone performance degree and taught students all levels. I tried some of the new models of asian made saxes and was mightly impressed ( wasn't expecting to be). For the price they really cant be beat. I have found the most vocal critics of these instruments have never actually played one. You may not pass these instruments down to your grand children (who Knows if they last the test of time) but have had one to loan out to students, even used it for doubbling on occasions and it rocks. The sound is closer to a yamaha more bright than dark and the action is spot on.
If you only have $700 and would like a new tenor I would be happy help you get one of the brands I have found to be very nice . email me <email> Also, I have many good used mouthpieces if you are interested. Best of luck( just one opinion ) Trevor
