I've just purchased a 6D and am having difficulty finding out what lcd viewfinder will fit..

Any suggestions would be appreciated.

Thanks!

Zacuto pro, got two amazing and needed. steve

That's out of my budget unfortunately.

Are there cheaper options?

I'm happy with the Hoodman Loupe on a 60D.

If I tried the Zacuto I'm sure I'd be spoiled, but the Hoodman has good magnification and an adjustable diopter. You do need to figure out how to attach - I'm using Hoodman's Hoodcrane, I wish it were easier to pop up out of the way one-handed, but it does work.

I bought this for my 5Dmk3. It's as good as zacuto
plus it has a eyepiece door. You can close it to prevent burning the screen under sunlight

I too didnt have the budget for the over priced zacuto, I bought the Carryspeed VF4 and was quite impressed with the performance, great price and does the job fine :)

Here is an Amazon link for the one I have been using on my 6D. I wanted to be able to interchange it on my 60D with the swivel screen, so it needed to be light weight. My Z finder was too heavy. This one flips up to see the screen directly and also has a diopter corrector. It is only about $50

i wasted 100 pound on cheap products, bought all sorts of viewfinders but only to bite the bullet on eBay used z-finders, best i have ever had reason being they don't steam up!!! the rest do!!

If you are interested I have a Zucato Pro 2.5X that is pretty much like new in the box. I sold my 5D3 so I don't have any use for it now.

I've used the Swivi on my 60D and 6D and they work like a charm. The only issue is that the mounting plate offsets the tripod mounting hole to the side a bit and make lining up other gear (Follow Focus, rails matte box, etc.) a real pain. For run and gun, no batteries and all is good.
