My parents want a smoker - probably not the best place to ask this... but what experience has everyone had with other smokers? Before I bought my large egg, I had problems with temperature control on cold days. They don't want to spend a lot, so I have been eyeing the Masterbuilt 30". Looks well insulated. Granted, I am not expecting outstanding quality, but for them, I think it'll be fine. What do you say?
