Michael, I have that same exact grill except it's hooked up for natural gas, not propane. And I absolutely love it!
I'm not quite sure how old this model is, as I purchased from the guy I bought my house from over 6 years ago. Needless to say, it still works perfectly. The burner and starter are all original.
I moved recently and was thinking about selling it. I was even offered $250 for it, but I turned it down. A grill of this nature would cost around $700 to replace.
Anyways, fantastic deal! Enjoy...
