IF you have the room the 22" with cover is a great griddle. It has two burners (1 on the 17") which gives you more flexibility. I have both 17" and 22". Walmart sells a 22" package with lid and stand at a great price. I have cooked 16 filet mignons to perfection (from blue to well done) at one time on the 17". Front grease tray on 17" makes pre-made windscreens readily available on Amazon. When my Weber dies at home I will replace it with a 3 or 4 burner Blackstone as I can cook anything (almost) on the Blackstone. Enjoy!
edit..heres the Walmart deal.
22" I didn't see this was a shipping item. I bought mine "in-store" for $149.
By the way... The stand (a $100 value) fits the 17" as well.
