A good friend of mine is a Captain/Instructor Pilot for Vision. What is it you want to know? They do mostly charter flights to a variety of clients, ranging from Travel Agencies (Cuba flying) to the US Government (Middle East stuff). They've also got some casino junkets that are open to the public.
They have good pilots (a bunch of extremely experienced guys from a now out-of-business worldwide charter company) and a good safety record. I don't ever hear anything bad about them. (And I know my buddy would not put up with any nonsense).
Just a question, where did you see tickets for sale? I'm looking for some cheap tickets for my brother and his family between the North East and South Florida. (I didn't know I could even buy tickets on Vision).
Another option, depending on where you're coming from, is Allegiant. They are dirt cheap, with safe, reliable service. You just need to be flexible on the travel dates as they don't fly every route, every day...
Hope that helps a little.
