I just recently noticed that Costco Canada has a new model of the CSO available, the CSO-500C. It's redesigned and adds an Air Fry option but it's got the same steam functions. It's $330 Cdn so about $250 USD, not a bad price! But I can't seem to find it in the US. Has anyone else seen it around?

Edited to add: I'd consider getting one of the new ones, but I still have the CSO-300 in the kitchen and one in a box in the garage! 🙂
