I have one of the first 750vsab I got it before jegs or summit ever had it. I had to give jegs the part#, they confirmed it was a real part then it took a couple weeks for them to get it then ship it out to me. Yes time is an issue for demon parts but it is well woth it. As far as tunning. I am not sure how to answer that. I am still new to carb tunning and still suck at it so I can't give a good evaluation if it is easy or hard to tune. But my freind had it preaty well dialed in a few minutes.

Demons tune MUCH better than a stock Holley does, you just have to know how to tune it. They are really touchy, which is good for fine tuning. Do a search, this has been discussed before.
