Mike,
If you think its bad to get stuff in canada, try where i am, the cayman islands! At least most places will ship to canada from the states, and you have selection at some stores. I have to get everything via online from the states without trying anything out. Its why I'm addicted to online reviews and probably ask the weird questions like "how heavy does it feel, etc".
As for the DR/AMK psk, I thought it was smaller... I don't need to add anything to the kit as I always have a water bottle around. Yes, I know, foolish to think that it'll always be there, but its a risk. Basically i'm still looking for that 'perfect' collapsible water container thats about a 1 litre with one of those breast milk closures (maybe more solid). Then I can put the psk into this for additional water protection and have that water canteen always with me.
Kris
