I am currently looking to replace my old charcoal grill that I've had for 10 years. I am more of a grilling person, (fajitas, chicken,etc) never smoked but love to start now. I am debating weather to get a heavy duty grill with a smoker box or just a heavy duty grill. My concern is that can I use the cooking area just like a regular grill in an offset smoker? Thanks My current budget is between $300-$600.
