Funny you should mention that. I was looking to add her to my preorder list as well.

The problem is the price of figures has literally gone insane in the last few years. There was a time I would just preorder a figure because I liked it and the price was reasonable. (Usually around 50-70 at most) So I had preorders stacked months in advance back then. Now the minimum is like $100 these days!
So coupled with the lack of space, and insane price that accompany them now, I am incredibly selective. I even like Aina's character and the figure, but she is not a priority and will probably be found in the used shops on one of my Japan trips for much lower than retail eventually.
Now these two are a prefect example of the crazy figure market. Both cost after exchange rate $170 a piece. Not including the shipping it took to get here.
And that price was only good because I ordered them a year out. And yes they sold out fast as well upon initial preorders. Now they are commanding 2-3x asking price which is nuts. I saw them in Akihabara running at $300 for Homura and $500 for Hikari! I actually expect due to the limited availability and popularity they will probably hold those values for sometime.
