What replacement cartridge for BSR Quanta 400?

I am eagerly awaiting delivery of my Supratek Chenin preamp, and am looking to tune up my old BSR Quanta 400 turntable while I wait. I eventually plan to get a VPI TT, but until then, the BSR will have to do. It's in great shape, since I've been out of vinyl since the mid-80s (I know, shame on me!), and it's been in storage, but I think I'll replace the drive belt, and upgrade the stock cartridge (the one it had when I bought it way back in the late 70's). I can't wait to hear vinyl sounds coming from my Zu Druids. I would appreciate any suggestions regarding an appropriate replacement cartridge. I'm looking for something that's very good, but not out of line for the quality of the BSR. Thanks in advance.
