Where can I find a Kodak lithium battery pack K223LA 6V?

I've tried amazon, but they don't have shipping to Canada.
It would also be beneficial if someone knew where I could get a hold of a rechargeable version of this battery with the charger (it was on Amazon, but same thing with the shipping issues),

* Also, if anyone knows, and because I'm a noob at this sort of thing (I've had this Nikon camera for a while but only used it for a little bit before the battery died), can I use both the normal battery pack and the rechargeable battery pack in the same camera, or does the rechargeable work in some and not in others?

Have you looked at this Canadian site?
