As much as I love the YF-21 and 19, the VF-11 will be the 'multiple purchase Valk' for me. There was only one YF-19 in the anime and only one YF-21, so that's how much will be on my shelf. The VF-11, however, was canon fodder, so I can buy as many of those as I want. If Yamato make the VF-19A and the VF-22, I'll get those, but there will only be one dark blue with yellow stripes YF-21, and one beige with red and black details YF-19 for me.
