I'm no Yamato 2199 expert, but have watched the series several times, including "Odyssey of the Celestial Ark." Of the Yamato kits available at this scale (or any scale, in my opinion), this is the one to get. Detail is amazing, considering the source is an animated subject, right down to the fighters. I've seen some builds done in such detail, you'd swear this was once an actual battleship.
It's also engineered to be lit with at least the main engine accepting Bandai's LED light sources (sold seperately), though you can certainly create your own means of illumination.
I've not seen anything on Amazon.ca that comes close to the HLJ price; Amazon.com would be in US dollars so consider the exchange. HLJ's lowest shipping price is $55.39 CDN so about $150 CDN shipped just for Yamato and not the upgrade kit. Ebay used to have some deals, but since the intial release, prices have soared. Obviously if you have someone in Japan who can grab one for you, that might be the cheapest route. Like I mentioned before, you have nothing to lose by trying HLJ as there is no cost to you until it's available for shipping.
That said, the 1/1000 version is a very nice kit and is 1/3 the price (again, through HLJ), and there are more ships available at that scale if you want to go for several capital ships. The 1/72 fighters are also very nice, as is the 1/12 Analyzer kit.
