Re: Mark VI...or SBA?
well better is a very relative term! It's all a matter of opinion. What's better for me might not necessarily be what is better for you.
Now, if you strictly asking in terms of value, the Mark VI is worth considerably more than an SBA, although even the SBA's are worth a pretty penny!
If you're going to play the horn, find the one that you like best; and like a couple others here said; don't limit yourself to Selmer. Try a Conn, Buescher, King, Martin, H Couf, or Keilwerth.
