Personally not a fan of multiples, especially macross. I'm in it for the unique transformations and solid alt modes. I get enough mold fatigue from what ends up being the same figure with a different paint scheme and unique head. I did grab 2x on the Arcadia 19, and Ozma 25 reissue. More for that safe keeping after waiting so long. Gonna keep them MISB. I also find that sticking to 1 copy of each means if I want to display them in a different mode I have to actually transform them (which is the fun part, right?).
To each his own. I think having display's with 3x of a valk is awesome. Looks great, just not my speed.
