Pretty much any French rep. with Ozawa is at least good, if not REALLY good. I have a very good "Damnation Of Faust" with Ozawa/BSO (DG). Be sure to try his De Falla "Three Cornered Hat" and "El Amor Brujo". I saw him give a truly great performance of the 3-corned Hat in S.F., clear back in the late '70s.
Some say that his Brahms with the Saito Kinen Orch. of Japan is a terrific set. You would probably have to import that from HMV Japan.
I'm generally not crazy about his Richard Strauss, but he did a really terrific "Alpine Symphony" with the VPO on Philips. I have it on a DVD-A disc, which has great sound. See if you can't find a used "redbook" CD of it someplace. That's well worth a listen. Also, his "Salome" with Jessye Norman and Staatskapelle Dresden (beautiful sound and playing) is worth hearing as well.
For something off the beaten path, try the Panunfnik/Sessions CD with Ozawa/BSO on Hyperion, or the DG Originals disc with his early S.F. "American In Paris" (terrific!) and "Street Concerto" (something like that) - Russo's harmonica concerto written for Corky Siegel. It's hoaky but it's fun.
I happen to like his Dvorak symphonies 6-9 with the VPO on Philips. They're not entirely idiomatic - a tad "teutonic", perhaps - but are still quite interesting. Each of those symphonies is coupled with one of the late tone poems of Dvorak.
Ozawa's "Turangalila" Symhony (Messiaen) is a great bargain on RCA. It's still one of the best ones ever. As for "Le Sacre du Printemp", see if can't find the remastered version of his much earlier Chicago recording of it.
