Okie, I was as much on the leading edge of technology as anyone on here or the other board. Over the last 10 years, I have learned my pit(s) using some of that technology. At the end of the day, I have come to the realization that I wasted thousands of dollars on gadgets that I don't use anymore because I don't feel that I need them to get the results that I enjoy. Others may get great rewards from these gadgets that I once thought I needed.
Some of that has come from simplifying my methods. Some of it has come from learning my pits for the things that I cook the most.
I am not saying the tools that I bought are not good. I am saying that maybe I should not have been as impulsive as I was in buying the next gadget because for me a simpler, less expensive gadget did everything that I needed.
A side story...several years ago a buddy of mine invited me to his lake house for the weekend. He knew I was into BBQ because I had brought some BBQ to his lake house several times to reheat and for people to enjoy. One time, he got distracted while he was attempting to grill sausages, burgers, and steaks. I stepped in to watch the grill for him because I wanted to eat and saw that left to his own devices he would have burned up what he was cooking. Everyone said it was the best they ever had even though I added no spices or rubs to what he had cooked.
After that, I taught him to cook steaks by pressing on the meat with his finger based on how he could press on the inside of his hand near his thumb depending on which finger he pinched to his thumb at its tip - a trick I learned from Steve Raichlen. The most outside finger and thumb feel was the close to rare. The most inside finger to thumb feel was closer to well done. From then on without me by his side, he cooked food his friends and family enjoyed without any technology.
Moral of the story. Cooking food on a grill is not as difficult as some folks make it out to be and depending upon the cook and his experience and knowledge doesn't require semi expensive equipment to deliver good results that people enjoy eating.
