A good friend sent me this link and I thought I'd pass it on here:

Just saw that Jack himself posted this link in another thread. I'd be grateful if a moderator could delete this thread. Thanks.
A Shure M97xE cartridge will track better than the Audio Technica, which will give your LPs more protection from being chewed up. However, it costs $89 (£50 ?). Might be worth considering.
