I'm a new(er) Q2000 owner, and it has re-lit my appreciation for Weber products.
My wife and I were debating the idea of replacing our 5 burner charmglow gasser this year. It is about 7-8 years old, and was in need of its 3rd set of tubes and deflector plates. The last time I replaced them, the full kit set me back almost the price of a new grill. This year, I was able to find a decent replacement set for $40. So my dream of a new Summit grill on my deck went out the window. I can't complain, though, the rest of the charmglow has held up pretty well for a $400 SS grill.
But we also camp a lot, and our boys are involved in sports that require a lot of weekends spent at sports complexes. Both of us were getting tired of packing sandwiches in coolers, and spending $50-$100/day on concessions/fast food was simply out of the question for us. After doing a fair amount of research, I chose the Q2000. It had the right blend of size and portability for what we need. (Unfortunately, I didn't do enough research, otherwise I probably would have gone for a red Ace model!). We've been using it almost daily since we bought it 2 months ago. We are a grilling family, we use our grills 3-5 nights a week, even in cold weather. It has been a blast getting to know the Q, and finding out how versatile it is.
We've become a huge hit among the other parents during the sports tournaments. They've become huge fans of us whenever they see us pull out the grill around lunch time.
On our camping trips recently, I rigged a smoker setup with it and smoked/roasted 2 whole chickens with it. I also roasted some jalapenos for poppers, onions and garlic for spreading on bread, as well as the traditional burgers and dogs. We're planning to pick up the griddle plate once our electric griddle we use with the camper has died. (It doesn't have too much longer, either.)
I credit the Q with steering me back towards a charcoal kettle. We've been batting around the idea of getting a smoker for a couple of years, now I think we'll just get a kettle and have that for a while as a versatile tool.
Edit: I bought the 2000 model, I decided to save the extra $50 on what I thought I was only an inaccurate thermometer. I didn't realize the lid was a different height. I don't know if that is still true with the new 2000/2200 series (I assume yes) but I can confirm that hasn't slowed down the versatility for me. I was able to easily fit two whole chickens under the lid very easily in a roasting pan. I will get back to you guys once I get the weber roasting racks and try some ribs, too.
