BTW, you can't buy any of the Prestige II + Napoleon products at big-box stores. They're only sold at the same specialty shops that sell the Lynx products.
You can get a number of Weber products at the big-box places, but not the higher end stuff either.
My Napoleon doesn't have a stainless cart, but the Prestige V models are all stainless. Though I'm not sure if any are available with wheels.
Take a look at
Lynx pricing at a pretty competitive store here in Ontario... They have decent Napoleon pricing too.
The Lynx carts are great and I do like the idea of cast brass burners. But as you can see, the prices here really (really) suck.
