Dave,
Myself and several others here have the Nu-Temp 701 and love them. I've had mine for about a year and a half now and have never had a problem. Many more here use the Maverick ET-73 which is cheaper and has the Hi AND Low temp warning feature the Nu-Temp doesn't have. The Nu-temp can receive up to 3 transmitters and display them in a rolling mode. There was a bad run of the ET-73 as of late but the customer severvice has been great...It's jut taken a while to get everyone up and running. All in all, if I knew I was going to get a good Maverick unit, that's the route I'd go. (I just ran into a really good deal on the Nu-Temps when I was looking...Couldn't refuse)
HTH,
