Just another "me too" added. I bought my Spirit e-310 last year and it was by far and away the best grill I have ever owned. Then two weeks ago, I bought a 22.5 OTG (was going to get the silver, but changed my mind and got the gold). Now I have only used the Spirit once in the last two weeks and used the OTG just about every other night. This kettle is very easy to use and control and I am getting better and better results from using it.
I have owned charcoal BBQs in the past and they were all cheap POS, which is why I went with gas in the first place. However, this OTG has changed my mind and it is almost as easy (if not as easy) to use as a gas grill. Not to mention with the added benefit of access to a cornucopia of knowledge on this, as well as other sites, one would have to be a total bonehead not to put out very good results from whatever cooker they decide to use.
A word of caution however, as you may have noticed from some of the other postings, that when you start with the kettle, you may religate the gasser to less and less work, until the poor thing gets totally forgotten.
