The first sax I got was a bettered '25 Martin Handcraft. I had no idea what it was at the time so lent it to a friend and bought a Hanson SA-8.
Then I bought a Selmer prelude tenor, good horn did me well, sold it on this very forum.
Bought Pete's borgani '50s maybe? soprano as an impulse when I was saving for a Yani T902. Then found out about the Walstein tenor, proffered it and got two saxes in two months! Madness!
I then researched the Martin and found out what a great horn it 'should be'. Got it sorted out, and wow! Lovely horn!
Didn't get on with my Hanson once I'd started getting better, always had a few niggles that built up over time. In the process of selling as it's been replaced by an '83 Yamaha 62 which is lovely, though I did heavily consider the Walstein alto.
Mouthpiece wise I have 4. A 4C for soprano, tried loads and bever found one that improved upon it anywhere near a reasonable price increase ratio. An otto link tone edge 6, which I no longer use, instead I favor a Yanagisawa 6 which I'm opening up to a 7* equivalent when I get the funds. I use a otto link super tone master 6* on tenor which I thought I loved but really quite dislike. Looking towards ebonite pieces, especially RPC, Yanagisawa and Vandoren though money is an issue again, as well I want something more open like an 8*
