The ET-73 is a great unit and I think you'll really like it. The nice thing for smokers is that it has 3 setpoints for the alarms. 2 for the smoker (too high and too low) and one for the meat. If you don't want to use one of the alarms, set the set point to a point out of range.
The unit also has a timer function. You can use it to count down and alarm to remind you of something, or use it in a count up function to time how long something takes to complete.
The major weakness of this unit is it's range. It doesn't have near enough. And worse yet, the receiver has no indication that it isn't in contact with the transmitter. It just continues to display the last temps received. The good news is the range problem is easy to fix if you're handy with a soldering iron.

I did both mods and I estimate that with the receiver inside the house, the transmitter can be up to 400 feet away outside.
The on off switches are delicate so be careful with them. The switch for the transmitter is inside the battery compartment. This is inconvenient, but it's for weatherproofing. The battery compartment has an o ring to keep water out.
The temperature probes can be delicate. Don't let them touch a hot grill or be exposed to excessively high heat. Also don't let the wires get pinched in the door/lid of your smoker. I'm considering buying an extra set just in case.
Using the unit is not intuitive. Read the directions thoroughly to know how to use all its features.
Don't get me wrong, the benifits of this unit far outweigh the drawbacks. But it's better to know these things up front.
