Question about cost of Gliders

I am working towards my Glider Pilots Licence and am
spending a lot of time on the internet trying to find
a suitable glider to see if I can afford to purchase.

I am looking for a self launching aerobatic glider.
The thing is that it I have not seen any costs being
posted on any of the sites that I visited. Can someone
tell me how much a Windex 1200C glider cost? and if
it is obtainable in the US? none of the folks at my
school seem to know .....
