I don't have source, but if you plan to use 13" blades you may have trouble finding them. I have a 13" Makita that is the perfect size for cutting tenons, etc, but I cannot find a 13" carbide blade for it anywhere. You may want to look around before you puchase the saw. Currently, I am using a 12" blade on it and it works great but I lose over a 1/2" of cutting depth.

I believe that I saw either the Hitachi or Makita for sale on the web from a seller in New Zealand, but that wouldn't be of much use to you because of the voltage difference between power in the US and NZ.
