I've sat on the sidelines quietly judging pellet cookers while also being secretly jealous for quite some time. I never really considered a pellet grill until weber announced the smokefire. I've been a weber fan for a long long time so it really piqued my interest, I was half a day away from pulling the trigger to get on the the pre-order list before I came across a Traeger Timberline 850 on craigslist and the seller accepted my very low offer.
So far I have loved it. It is very a very handsome grill (I call it middle-class chic) and I have turned out some very good food on it in the few weeks I have owned it. The only downside is having to take the guts out fairly regularly to vacuum it out, and I can tell the heat deflector is going to be difficult to keep as clean as I'd like. You also have to ignore all the trolls online that tell you your pellet grill isn't a smoker, and call it a driveway oven. Screw those guys.
Not sure if any of this helps, but it sounds like you are in a similar boat I am in, so I thought I would share my recent experience. I can't wait to get some real world reviews on the smokefire!
