Thank you ST and PD!  Interesting information and yes, I went for the new Coleman canisters precisely because I have to travel to Ely or Crane Lake to get the others, when and if they have them.  Anderson's and LaTourell's both had the brand specific canisters this summer when I needed them.  Piragis also had them.  Prices were all about the same and all had canisters mid-summer when the paddling season was "on".  I noticed in my shopping at WalMart that they also have a smaller version burner, more like the PocketRocket.   8-)
