I recently bought Veil with Aziza and Smooth as Silk with Katia and would recommend both.
Aziza demonstrates moves that you can use with a rectangular veil of any fabric. I already knew a number of the moves that she teaches on this video, but there was quite a bit of material that was new to me, too, including the turn that she does in one of the IAMED shows where it looks like the veil is spiraling around her.
Katia teaches technique designed for a silk veil. She uses an extra large veil, but most of the moves also work with my standard-sized ones. Almost all of what she taught on this video was new to me: lots of moves designed to let the fabric ripple or float.
Now, I'm not selling my copies of these, of course, but I can recommend Kevin on Ebay (user name: oceanstatemedia) as a vendor. If you let him know that you're a Bhuz member, shipping is free. He's actually selling both of these DVDs right now as a package:
