Those things in my opinion are the reason many people try their hand at smoking and quit. Those things being cheap smokers one can get readily that dont work well and dont turn out good BBQ without lots of mods and blood, sweat, and tears. I started with one of those and nearly quit. My advice do research spend more money and get a better smoker. Or better yet if you want cheap build a good UDS for about the same money as the Brinkman ECB.
