Ok, so I am in love with this dress for my wedding...

It's from the Spring 2009 White Chocolate label by Scott Corridan made for Kleinfelds. I have a very similar Vogue pattern and my mother and I are prepared to make it ourselves, but... if I could find a gently used one for a decent price, it might save us a lot of work.
Anyone have info on buying this dress new or used?
Thanks in advance!
