Awesome site as I've been lurking for about a month now seeing whats the best brand ES i could get. Well today I found a smoking deal, a MES 30inch for $90 Brand NEW! Only thing missing is the temp gauge. So a few question, do I need the OEM therm or an aftermarket would be sufficient? Secondly, this is my first smoker EVER so what are the process or processes to "break in" my new smoker?
