Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
LarryB - I would strongly recommend looking at the Smokin-it Line of all stainless steel electric smokers. You can read about them here at SMF, and at the Smokin-it site. Worry free and problem free, and with a 3 year warranty. They are a solid investment.
You may want to switch to Propane, just as easy to use, without the electronics to worry about. I have charcoal, elec, & gas, and end up using the gasser most of the time.
