I had a quote for a digital controller from Germany, it wasn't cheap and I've not bought one yet due to house buying costs
My thoughts are that it is essential if I decide to use the Traeger in competition because I need consistent cooker behaviour. At home I've been generally satisifed with the quality of the food coming off but there is a varyance depending on the weather. When I cooked on Saturday it was so cold that smoke wasn't hot enough for my liking, but medium was too high for what I was doing.
I might have to get osme of these frog mat things though.
