I use the $10 Weber therm through a cork in the top vent. (Cappy invented it) Never had any problems. Won a contest that way. Larry has seen it. Plus it makes it easy to calibrate the therm also. No tools needed.
Finney had an installed therm go bad at the same comp. He was using Mavericks anyway so it did not hurt him any, I don't think. Then again, Finney doesn’t need any help. He knows way too much as it is now. :twisted:
I agree with Larry, Nick and Puff, cook with it a couple of times before making any mods. It does quite well right out the box.
Just my .02
