I am really interested in these figures, however I have a few concerns 1. Alot of people complain that the knee joints are brittle and easily break, even on the 2.0 star GGG set. Is there a tutorial that shows how to effictively fix the knee joint? How common is this problem? Also is it presant in all the figures "gaigo, fighgar, 2.0 gaigar". 2. Just how good is the plastic quality on these sets? For example will things break off when posing the figures? "I have seen a pretty spooky thread on robotjapan where someones fighgar's arm assembly practically came totally apart" 3. How much should I pay for these sets? Should I shell out for the "GaoGaiGo" set and get gaofighgar, gaigo, and stealth gao 3? Or should I get them seperately? 4. Should I just wait? Do you think that Takara or another company will be making a better and more affordable set soon?
