I like smoking with charcoal and lump and have a steady supply of quality splits/chunks. What's a good value priced retail cabinet smoker for a backyard bbq'er? Currently using a MB800 but getting that itch to move on to something else. Want enough space to do 4 racks of ribs, or 2 briskets (not together). Just a smoker, not looking for a unit that can also function as a grill.
