Depends what brands you're looking for. I have specialized in German brands. My
Julius Keilwerth,
Max Keilwerth,
Hammerschmidt,
Oscar Adler, B&S (both
vintage and
modern), Hohner, etc, etc, pages are the most complete you'll find anywhere (including German). I work together with German saxophone historian, Uwe Ladwig, to bring his work to English-speaking audiences, and then further his research by doing my own using his as a springboard.
My
Vintage European horns directory page gives you a listing of the brands I've done to date. Next up: H. Couf.
