Projector Screen Questions

[Unknown450]

Hey all!
I was planning on buying the Sony Z9D 4k/3D tv but looks like it is now sold out at Best Buy and I'm guessing they won't get any more.

So in a couple months I plan to buy the Epson Home Cinema 5040UB projector for the 4k and 3D.

Right now I'm trying to plan ahead and do some research on the screens.
What I want for now is an 84'' inch(later I will go bigger when have more room).

Any recommendations on a good 84 inch screen?
I've heard Elite screens are good, but they have different series...
Manual, Spectrum, ezCinema etc. And I have no idea the difference between them all. lol

And I've heard reflective screens are an important element for a good screen?
Was going to ask if I needed a special screen to see 3D but saw an answer in another thread that as long as I have a 3D projector I'm good to go.

I don't really know anything about projector screens so any info/help would be appreciated.
