Time for a new cartridge.

I will need a new cartridge by this winter, but I now have some time on my hands to take the time to do a new cart setup so  am looking.  I have a Audio Technica AT33RTG/II it is my first LOMC.  I really like it and is a good price point for me I think I paid $525 for it.  Part of me says just get another one and part of me says I like the rest of my system so this is a chance to change something try something new. Any suggestions around this price?  I can go back to MM. My Music Hall turntable came with the Mojo cart which is made by Ortofon, I like the AT better. I listen in a 12 x 22 living room. I listen to mostly jazz, some bluegrass and folk. Thanks.
