I'm about to use my MES 30 for the first time. I've done some research on Amazon and some other places and Maverick seems to be a big name in remote thermometers but I read a lot of complaints with those. In fact, I saw no clear winners among any brands. I thought I might be able to use my Taylor digital instant read which is a hand-held type that I use in the kitchen but someone responded in another thread that it's not good to open the door while the smoking's going on. I don't need a remote control device sonce I don't mind going into my backyard at different intervals to check on the temp. Is it that bad to open the door to check the temp once or twice? If not, why can't I use my kitchen thermometer instead of buying a specialty BBQ one? If the door should remain shut during smoking, what would be the best, around $30-40 smoker top, non-remote thermometer to buy?
