I had the SmokeFire Ex6 which I honestly loved! When I saw that Weber came out with a new and improved smoker, I just had to have it. I purchased the Searwood XL 600  from a local bbq store, brought it home and put it together right away. Quality is top notch and with very little difficulty had it set up in no time. What a vast improvement over the SmokeFire. The Searwood heats up so much faster, uses less pellets and is extremely quiet. The redesign of the pellet was much needed and puts me at ease for those long overnight cooks, not having to worry about any pellet feeding issues. Only complaint, would have been nice to have gotten a complimentary bag of pellets. Weber, you got it right! So happy with my purchase
