Go with the LM-3S, more memory room and easier to add a non-RP Keep-Alive.
I'm in Canada too. Last time I checked, Yankee Dabbler had decent pricing and free ship to Canada. Bill, our awesome RPUG keeper, sells them as well, but he can only ship to the US. If you are close to the border or have a US connection that might work as well. Check him out at pdc.ca
