Highly recommended! Just Do Not Buy One! This guy is ripping $$$ off of yankees, good for him. Build your own from a 55 gallon drum...they are incredibly simple, and efficient beyond anything besides maybe a Big Green Egg. UDS (Ugly Drum Smoker) is the most common name.
I am a very happy owner from my own build. I would guess I have at the most $100 to $125 invested, and maybe 3-4 hours of work.

I have no heat sink, it is not needed. Three air intakes are evenly placed around the circumference, and centered (if I remember correctly) 1.5" off of bottom. Two are removable caps, and one a ball valve for fine tuning. I easily get 15+ hours of a steady burn at whatever temp I set it at without doing jack, as in absolutely nothing...go to bed if I am smoking overnight, or living my life not tethered to constant temperature monitoring. 225* is what I am working at now for ribs, butts, birds, chuckies, pastrami...may drop a little lower (215-220) for my next brisket, which actually will extend my burn time...like I need it. Six or seven glowing briquettes is all that is needed to get things going.
The lid is off of a 22.5" Weber grill and lends another control of air flow with its basic, but surprisingly very effective adjustable vent cover. The lid also creates more space for meat (think turkey, beer can chicken) versus the flat lid offered from the website. Both levels of grates are also from 22.5" Weber grill.
Clean up is very easy. My charcoal / wood basket is attached to a pizza pan by 3 stainless steel bolts with roughly 3" clearance. The clearance allows for air flow from intakes mentioned, and space for the ash to collect. A handle allows for easy retrieval of the basket and ashes in one move.
