Hi, I'm looking to upgrade my Louisiana grill CS-420 to a Primo XL. I'd prefer to smoke year-round and feel that the Primo XL would perform better in our colder climate during the winters. The CS-420 is 2yrs old and works perfectly. I have upgraded the control panel to the digique-II and have added the hopper extension. Willing to trade but may be difficult to do as I am located in Toronto, Canada.
