First of all - all these people throwing around edition numbers ... they don't know ****. They are guessing. Maybe 600 was an official number for the Toy Sapien store in Japan? Maybe it is world wide? youtubers often say - "I hear this and that is VERY limited" but I think it is often to justify their own purchase to themselves. If it is rare, it is an investment and therefore okay to buy iy. If you just buy it cause you like it ... there is something wrong with you. Again, buy it if you LOVE it. Otherwise don't.
I think it's a strange move on Hot Toys part to limit the release of this, but I guess sometimes it is good to create a hype around a product. I don't know. I am not in marketing.
If you live in Europe (like I do) collecting Hot Toys is very expensive. I suspect Australia is the same. But if you want Marty, SS is your best bet. Toysbuyingagent is sold out and Toyswonderland is CRAZY expensive (I never buy anything from them), so SS is your only option. With shipping and taxes and whatnot, Marty would cost med 435 USD. Thankfully, I have the first one. This HS is not that much better (if at all) and if I want the dog, I'll pick up a third party dog, probably a better looking one too.
For all those outside US who missed out on the first release, I feel for you. It's rough. Let's try to help each other out, so if someone hear something, pass it on.
