I had no idea these sites existed till you told me. I only know about 3 gundam sites outside of AmazonAssuming the AB Parts end up being P-Bandai as well (a good bet as those who would know have hinted at that being the case), I would keep an eye on Nippon-Yassan if you're going to end up with those as well. Paying $40 at Gundam Planet isn't the worst and better than missing them completely, but you'll save a good amount of cash going through one of the Japanese middleman sites like Gentei Kits or N-Y.
