In the Classical category - of course, the small Europeans are good (like those mentioned above) - but IMHO, by far the greatest "sleeper" is MHS (Musical Heritage Society). Many of their reissues are sonically better than the originals (mastered beautifully by Bill Kipper at Masterdisk), and many of their home-brewed recordings are spectacular (especially those supervised by Dr. Kurt List). When you see these for $1 in the Thrift stores - Buy Them! (unless you live in the S.F. Bay Area :)
