Yep - I've taken to using a piece of crumpled up foil to keep it centered in the hole. Works ok. I think I have the new style probe that can be replaced, but for a part at $90+ (ridiculously overpriced given the cost of any good oven thermometer probe with wire mesh outer sheath), and with all-negative reviews, I'm not very happy at that prospect. What has happened to CS with this new lousy forum, and seemingly ever-increasing prices for inferior replacement parts? Customer service on the phone seems ok but that's only two or three employees with dedication, not necessarily reflecting the company business model, which seems to have gotten less admirable.
