It looks very interesting, but at that price, they're competing with a lot, including ceramic grills (which is what I have). Maybe the Weber is better than a ceramic, buy you're also into the price where you can get two grills (one ceramic/Weber for everyday grilling and one for smoking).
As with everything, there are benefits and detriments and people spend their money however they spend it. From my perspective, I'd consider a bunch of other grills while considering this one (and if it's like anything else, the "perfect" grill/car/amp/system usually doesn't exist). Even my ceramic, for instance, I'd rate as only "good" for smoking. It can be difficult to control at times. However, I went to bed December 31st with a pork butt in the ceramic cooker, and woke up the next morning to great pulled pork and not too hot of a temperature (less than 250). And if I'd have had more time before going to bed, I'd have been able to dial the temperature in a little better.
