Sorry this is a little late, but I'm still trying to work my way through all of the info here.
The themometer cronyism linked to is very good. I have 2 inexpensive multimeters from Sears with the thermometer function built in. One was $20.00 and the other about $32.00. They both came with probes that have an adapter for the K type probes and you can plug the ThermoWorks K type probes into them.
For the remote, everyone seems to prefer the Maverick, but I have the Oregon Scientific talking thermometer and it works great and is very accurate. The talking part can be irritating, but you can turn it off by pushing any button on the thermometer when it starts talking to you. I actually like it because I'm hard of hearing and if I'm off doing something else, I'll hear it remind me when it's almost done. I think they're all a little quirky. Sometimes I have to play with it a little to get them to communicate, but mine works anywhere in my house without losing the signal, once they're communicating.
I've measured the temps in my empty Smokette and in mine, it is about 10-15 deg. warmer at the top shelf than the bottom and cooler at the back than the front. The wood also seems to burn hotter at the front of the smoke box, so I try to get the meat closer to the door.
When there is meat in it, the temps drop a lot, but as the meat comes close to the set temp., the smoker temp. starts creeping up to stay above it.
I love my Smokette. All I do is check my remote thermometer occasionally and let the Smokette do all of the work and make me look good.
