so the smoker that came with my propane brinkmann grill just isnt going to work. the wood/water pan is just too small and i have to replace the water almost 3 times an hour other wise the wood burns up in 10 min. plus it barely holds a handful of wood i would like to get a charcoal smoker on the cheap. looked at the $70 brinkmann vertical smoker but read bad reviews. whats my best bet? i really dont wanna spend 300 on a weber smoker.
