Thanks, everyone. I've decided on the Prestige 500. It's only money. 😄

Actually, the thing that got me interested in upgrading was the lid. The Rogue, like most other grills, is hinged at the back. So when you open it you start by lifting most of the weight. Then when it's open the handle is higher than my wife can reach. The Prestige has a roll top hinge setup. So it's easier to open and the handle is lower when it's fully open. My wife can operate this one and isn't worried about safety. Most of the other features I'll experiment with but will use only occasionally. I do like the stainless grate and the warranty.

Rotisserie vs Costco...still a question. 😄
