Definitely worth the money. The only problem I have with my et-73 is the range is horrible. That and it doesn't give you any kind of notification when you lose the signal from the transmitter, and would display the temp when you lost the signal. Can be very deceiving.
They seemed to have remedied both those issues with the 732.. Up to 300' range from the transmitter, audible lost signal notification, as well as probes rated to a much higher temp, although I never had a problem with my probes, even at 375 for poultry, well until the meat probe died recently, but it probably lasted for close to 100 cooks, which seems reasonable. Anyone find out the price for replacement probes for the 732?
