This is an excellent grill.  I bought this to upgrade from my 8 year old 3-burner Spirit.  I love the side burner - especially to use as an alternative to my indoor gas stove top (so there are less cooking odors in the house).  Not too difficult to put together.  One thing I don't like (about any grill) is the steel grates.  Can't wait to upgrade to the PECI grates when available.  Also, excellent customer service.  I received the grill but was missing one part.  I called on a Saturday and customer service answered.  Got the part shipped to me to the following week and was good to start cooking!  Also, the BTU output is excellent.
