I bought the Cannular, but have only messed with it for 3-4 cans so far. Seem like a good unit. It will be pretty easy to adapt to the regular 16oz cans (left) vs the 16.9oz cans the machine is set up for. Just add some washers/spacer on the table that raises the can up. They use the same ends, so the only difference should be can height, just in case the 16.9oz cans become hard to get.
You can get the Canone cans on ebay. 271 shipped for about $100. I bought the full apreture 360 lids and really like them. You can drink from the can and get the full aroma of what you are drinking.
