I owned a Glider for several years and later experience has taught me it was nothing special. I also owned the predecessor to the Sumiko Blackbird, the Blue Point Special... feh. In general, I have come to prefer MM or MI cartridges to high output MC cartridges like Sumiko and Glider. In the same price class, you might consider Clearaudio Virtuoso Wood. Though I have never heard it, it has received rave reviews on the MM thread. Plus, it will have a high output suitable for your phono stage. Also, I am a fan of Ortofon, though I have not heard the 2M Black; I bet it's good. Finally, do not ignore SoundSmith MI cartridges in that price range.
