These will all do a Great job grilling or smoking.
The Char-Broil charcoal smoker $89
The Meco Water-charcoal smoker $57
A smoker similar to one above.
Brinkmann Split-Door smoker $74
The Brinkmann Grill King pictured in my above post is discontinued, but a similar model is available. I think I paid $80 for it.
A hint to make these charcoal grills last and the bottom not rust out. Make sure water can drain out and not stand in the bottom. Drill 1/4 inch holes in the corners if needed to insure drainage. I did my Grill King and it’s now 10 years old with no rust and it has always sat outside in the rain.
