If you like the Shelter 501 you might want to consider the (more expensive) 5000/7000/9000 line of cartridges
Experience with Sumiko Celebration II
Anyone here have any experience with this cartridge. I am budgeting to replace/upgrade my Shelter 501Mk II. I am generally pleased with the shelter, actually very happy with it. But a cartidge does not last forever so I am starting to look for replacements. Do to the fact that I live so far from any dealer it will take some time to audition some options so I want a manageable A list. Thanks, David.
