I just moved to Texas, and while smoking on my Weber Kettle made some good BBQ, I want to step up to an offset firebox. Though at this price point, "step up" may be a bit of a misnomer. My local HEB has a Char-griller Smoking Pro on sale for $160.. I looked up some mods and for $30 or less I can mod it to improve performance. Is this just a waste of time? Is there a better smoker I can buy off the rack for around $200? Thank you!
