Lou: You can go back, if you want to. It is a matter of finding the time, location, and desire to practice. I've played for 50 years (now 67) and never gave it up, so I don't know how it would be to try to start over again. But I know others who have.
Many of the cheap (don't confuse "cheap" with "inexpensive", either) sopranos around these days (and it appears that yours is one of them) can achieve a decent sound alright. It is the "feel" and the "look" of the hi-end and/or vintage American sopranos (like Buescher, Conn, and The Martin) that will be lacking, plus the hi-end sopranos' scales (intonation).
It may pique your interest to seek out a good soprano and compare them. Another suggestion would be to seek someone's advice (someone who KNOWS) about easy playing mouthpieces and reed combos - THAT may make the comeback more enjoyable. DAVE
