Price Check: Summer/Windy Wings

[StillandSilent]

I hope I'm in the right place, I couldn't find a forum just for price checks. 
I'm looking to add Summer/Windy wings to my collection, to go along with their custom babies.  The only one I have is Sun Glider, except for a bait Little Flitter.   
I know that Windy Wings tend to be harder to find, but I'm just looking to get an idea of what they generally go for these days.
