Saqra's Video (& DVD) Series - Choreographed Belly Dance Routines
She has several "no frills" dvds. I have her veil technique reference, which is a reference of different veil moves, but done in a way where you can string them together in to a choreo if you want. She also has about 5 solo choreos and 2 or 3 troupe choreo dvds. Also several other reference dvds. I have also viewed her beginner reference and one of her solo choreos.
I personally like her style, it is easily transferable to other stylings, her breakdowns are clear and precise and you don't have a bunch of warm up and cool down taking up disc space, it is all just straight dance. There aren't any fancy sets or backdrops, but the info is solid and there is a ton of info on each dvd. There are also choreo notes that come with the dvds.
