Teaching others to can

Hi Friends,  I just got back from a circuit of classes in Oklahoma teaching people how to use a pressure cooker. My pressure cooker line (Fissler) isn't recommended for canning and while I have canned in an old pressure canner (years ago) what I teach is all hot water bath canning.  My classes are wanting recommendations for pressure canners to purchase so if you have one you really like please let me know what it is and why you like it.  I can't teach pressure canning (there are liability issues with that because of the issue of non-acidic foods, shelf stability etc...) but I would love some input for myself and to pass on to my classes.
