Look for an Emu Planet Phatt or Roland JV-880
One will get tired of the planet phat sounds as I did after using it for about a year. The sound set began to bore me after a while so I got rid of it. There are other better alternatives if you'd like to stay with the emu stuff. The proteus 2k, vintage keys, & planet earth are a few examples. I still use a roland jv-1080 w/ a couple of expansion boards in it. It does a nice job of adding its own flavor to my sound arsenal. Don't know if you own the MPC 4k, it's a sound module itself as well. And best of all, you can load it with anything you can find that'll fit your taste.
