I wonder if people know the difference between the classic and Mk4 Thermapen.... I have the classic and would much rather have a Mk4 due to the fact that it's the SAME thing with more features, but it wasn't out at the time I got mine..... Having a backlight for grilling is huge.
davidJ18I voted mk4 just for the back light, there are alot of times im smoking at 3am and it would make all the world of difference having the backlight.
