Hi Karen,
The result of the clear pot discussion was that a few of us Edmontonians joined forces and ordered from First Rays orchids, as we could not locate a source in Canada. Their website has a good selection with pictures so that you can be sure you are selecting exactly what you want. TeresaE coordinated the order, so I am not really sure what the extra charges were for the whole thing (duty, GST etc). It was pretty reasonable. I have also ordered from Charley's Greenhouse in the past - very quick, sightly more expensive. Are you looking for only a couple of pots or a bunch? I could probably help you out if it's a couple or three.
The Orchid Society of Alberta Show promises to very good. Also looking forward to it. There will be many vendors with plants to sell, some are accepting pre-orders. Be sure to check the OSA website - there is a discount coupon for admission.

Not much to say about the Den. Only ever grown den. senile, unicum and secundum. Bare canes were a seasonal thing prior to flowering. Mine grew in a windowsill with the seasonal temps of the window!
