Thank you so much for the kind words! I think you would be very happy with a smaller pellet grill / smoker. The wording changes depending on how you are using the device. For instance, if you are cooking at low temperatures you will get a stronger smoke profile then if you burn a pellet smoker / grill at its higher temperature range. One thing you could do for steaks is cook them at the higher range thus being able to get a sear much like you would on a direct heated Grill service, for instance on your Weber. Another option would be to cook the steak in the reverse see your method, by bringing it up to temperature at a lower smoker setting and adding some smoke flavoring that way, then removing it and bringing the smoker up to its higher settings so you can finish off the steak with some of the effect you would achieve on direct flame. I normally do this by bringing the steaks up to about 15 degrees below where I want them to finish. Then, I finish them off at the higher temperature to where they are about 5 degrees below my target. This usually means a few minutes on each side but I use a Thermapen to be sure.
In true Yoder fashion the 640 is not a fancy cooker with lots of shiny things, bells and whistles. Don't mistake that for poor craftsmanship, the Yoders are all built to the highest quality standards. They just happen to be more muscle car than sports car. Big, bad ass, built to last American muscle car that will blow the doors off the competition on your back deck or on the comp trail.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
