I had the previous version of this grill for about ten years and was pleased with its features and performance. Moving to a new house -in a different state- prompted me to retire and replace the old machine. 
The newer model has a better battery powered ignition system (my old one's flint spark stopped working after about five years,) an improved ash catching bucket, a  center removing grill option and a better thermometer. It also has a timer which is kinda lame and I don't use it. 
Otherwise it's the same cooker I knew and appreciated, and I expect to get at least 10 years of great grilling out of it.
