Welcome to the forum. I have been through a few charcoal smokers. I was in the same boat as you. I hated the winter for smoking and it was a pain to not only clean up, but to keep constant temperatures. I even had the guru with the fan to help but it just got old. I finally settled on the SM25 and have not looked back. The only thing I lack is the true smoke ring but I don't really care. My products for the most part are better then ever.
The wife and I ride motorcycles and found that during the nice weather, we never smoked on the old smoker. After the sm25....we smoke a ton. I went and bought this wirelss thermometer.

www.join.me and it broadcast's my desktop. Using their app for android phones, i can monitor my meat temps at any time I choose. A couple weeks ago, I set 2 pork butts in and waited until the smoker was going for a couple hours. We went off on a 150 mile bike ride. I checked the meat temp from the top of one of our mountains and knew I was still 4 hours out. Nice piece of mind knowing the smoker is dead on the money and I don't have to babysit.
