Yeah, the Hi-Metal range looks great! Just sells out so quickly -- partly my fault as I don't keep track of when things go up for preorder.
Spoke too soon... got a new Ramjet this afternoon
I've dealt with Bandai a few years ago to get a replacement (for a part i broke) on a Super HCM pro without hassle too. Though it broke mostly cause it was tiny, they didn't care i'd done it, in fact they express posted it to me since at the time, my wife explained we were coming back to Australia in a few days. Pretty sure that toy had been out for 6 months at the time as well!
I guess that's the advantage of being in Japan instead of outside as there are no real support outside Japan.
