Well here it goes...
Main use Studio Work with Flash ...so my main aperture is f/8 - f/16 and main SS is 1/200 sometimes 1/160......
the EF 70-200mm f/4L USM Lens non is goes for about 700
the EF 70-200mm f/4L USM Lens IS goes for about 1300
the EF 70-200mm f/2.8L USM Lens for about the same as above
the EF 70-200mm f/2.8L II IS USM Lens is out of the question too much money

since studio work is my bread and butter should i pay more for the f/2.8 non is or can i save and get the f/4 non is or stay in the middle with the f/4 IS ......
ok go
I think you need to tell us what other lenses you're using and why you're thinking about the 70-200 specifically. If you're shooting on a crop it's definitely going to be way too long unless you have an enormous studio.
Also, at f8 and upwards you're not going to see a remarkable difference (if any) in the L compared to other "lesser quality" lenses. I'm not sure what lights you are working with, but personally, I'd put the money towards quality lighting and modifiers - that will have a larger impact on your photos than the L.
