One of the instruments I bought for my school early on was a baritone saxophone. Without enough money to purchase the standard, school-approved, Yamaha YBS-52, I opted for a Keilwerth ST-90. It was not the best choice.
Now, it is true that the school baritone saxophone is often abused, mistreated, and uncared for. But the instrument we received has never been as good as I hoped (except it did start off nice and shiny). Tone is a little thin, but pitch (especially in the upper register) is difficult to control. The keywork has been solid (getting repaired just fine after being banged around and dropped), but the thumb rest seems poorly designed (it slips and slides around the screw that is supposed to hold it). The shows more than its age (8 years)--after all, it mostly stays in the band room. All that said, I feel pretty good about putting the Keilwerth bari in the hands of a 7th grader. I'm not worried about it getting busted, and so it still serves a useful purpose.
I present all this about the Keilwerth bari to provide a contrast with the Schiller model we got two years ago. It comes in a hard case (with wheels!) and our model has a matte gold finish. I have only let the older bari players (high school) play it regularly, and so it has perhaps been treated a little better than our first bari. It has suffered some knocks and scrapes, but the finish still looks good. It has had a couple adjustments at the shop after these bruises with no problems.
The sound on the Schiller bari is the best part. It is warm, plays in tune throughout its range, and independent sources have complimented it. We used it during both jazz bands's performances at the Eau Claire Jazz Festival, and the judges who heard it in each group praised the players and the instrument itself.
At this point, I feel pretty good recommending the bari we got.
