Advice before understanding the problems bjroosevelt is having with his 16M seems premature.  The complicated spring pressure issue is with the 10M LH table rather than the 16M table, which is relatively simple and lacks G# articulation.

A little off topic here....but my Conn has a few problems.  I suspect you have larger hands.

For starters - 

1). My left palm keeps bumping into the palm keys on my Conn 16M. -  the result is an airy, high pitched, missed note. 
2). Every time I try to play High-D, the bloody instrument tips to the side. 
3). Key action is slow because of the way the left and right hands line up, as well as how the fingers and palms need to rotate to hit the notes.
4). Right thumb always hurts when I am done playing.  (Have had an adjustable thumb support installed, but it isn’t perfect). 

Yes, I know there are partial to full solutions to all of these problems (like key risers) and I agree that a professional overhaul would help the Conn a lot. ........but at the time I didn’t want to invest too much into a horn that you can resell for $700 and isn’t so ergonomically well designed.  I won’t have a problem getting my money out of the Mark VII if I choose to resell it one day. 

Conn is in the basement still.....after I get my messed-up, ”Church Fundraiser”  ‘53 Selmer SBA, original laquer/resonators, Tenor sax back from PM Woodwind, I might have someone take a crack at the Conn.

Have never played the SBA before.  I wonder how different it sounds from the Mark VII.....Just want to be able to play it once....it is going to be sold and the proceeds are going to charity. 

The Bundy II is a solid student horn.  If it's in decent shape it should serve you well while you're learning the basics and developing your technique.  That's much more important to you at this phase than worrying about this or that horn.  There's plenty of time for that later when you know yourself as a player and what your criteria are for the horn you truly want.  The most beneficial piece of equipment to upgrade, once you have developed your embouchure, is the mouthpiece and that won't be a simple decision to make hastily.  

The TS200 is marketed as an "intermediate" horn, whatever that means.  As far as I can tell it's a term for fancier student horns.
