Guys, thanks for the advice. Some good options mentioned. I'm still open to a number of cartridge choices. I may go with a more reasonably priced option in the short term (perhaps the DL 103), and save to get something better longer term. Another option might be to jump on a bargain used cartridge - the ZYX Airy 2s looks inviting at $925 for example. Still, this is an expense I hadn't anticipated, so am weary of spending more than $800 just now. Does anyone know where I can still pick up a new Denon DL103, or where I can get a good deal on another Shelter 501 Mk2? The Sumiko does look interesting too.. Anyway, thanks again for the advice. Shame I can't salvage this Shelter ;-(
