IF all else fails I know Mandarake will at least have March for a fairly decent reasonably price, BBTS pre-order price for March is insane, I only pre-order Sunny over there just due because that month is my Birthday, and I'll use my B-day money on her pre-order.
Right now your best bet for Beauty would probably be Mandarake right now. That is if N-Y doesn't have an absurd mark up on her(if she's even in stock).
Peace and Happy are good. They come with a lot of faces and hands that get their signatures expressions across very well. And given the fact Peace and Happy are almost always on sale these days, they are a steal at discounted prices IMO.
