Beamax R-Black or GrayWolf 2?

for an Optoma HD72i?

It's a small room (garage conversion) with white walls.

trying to decide quickly for the Discount TV package!

thanks,

(I'd already posted this in Projectors, but couldn't figure out how to move it!?)

 

Is the Beamax R-Black screen like the sony one i heard about ages ago?

Im looking for a new screen and the gray wolf 2 looked pretty good for the price but if these are the black screens i heard of and are better plus reasonably priced i may have trouble choosing.

I would like to know more about these as well and a reputable place to buy when the time comes, thanks.
