There are a lot of decent instruments out there these days, but there are some to stay away from too. The main pro to buying a well established name like Bundy or Yamaha is that if you do your research and get a used one for a decent price, if you decide to sell it later you can always get your money back out of it. That is not the case if you buy new or a brand that no one has heard of. Some lesser-known companies also produce instruments of inferior quality, which will just lead to frustrations by a beginning player. Welcome to the sax world!
