I got an Alto in the post yesterday. A few comments:
1) This is the most durable feeling toy I've brought since, well, a chunky monkey (well, a Jetfire, 20+ years ago).
2) Posability is decent, not great, thanks to the leg design.
3) Its likeness isn't spot on, in comparison to the CG, but I only noticed that when I deliberately went looking for flaws. It's beauty otherwise.
I think what is causing the contraversy with these toys is a difference in design philosphy between Bandai and Yamato. Bandai seems to being going for "toy", whereas, from what I've observed, Yamato makes display pieces. This is a uninformed opinion though, as I have yet to get a Yammie, so please forgive the sweeping generalisation, I'm just going from what I've read here.
