Get a MasterBuilt smoker..They cost a little bit more(about $199) but they have features the $99 don't have .
They are insulated and have a thermostat. It comes with a menu book and complete direction. It is easy to load and all the racks are stainless steel and come out for cleaning. They are big enough for several racks of ribs, chickens and other stuff or just one item for just the family.
I had one and gave it to my son when all the kiddos left. He uses the thing all the time and it is just worth the investment. You can also get one larger for about $300 if you want to smoke for an army..Once again they are worth the extra investment..
Hope it helps..You can see videos on You Tube just type MasterBuilt smokers..and good luck..
