Collapsible Reversible Chroma Key Backdrop

[CF01]

I'm looking for some opinions on collapsible reversible chroma key backdrops.

Anyone have any particular ones that they have had good or bad experiences with?

Is there a best type of fabric for these when it comes to avoiding wrinkles or getting nice diffuse lighting?

I'm on a pretty tight budget so it would be nice to hear if some of the cheaper ones work well.

Thanks

I have had good luck with the Digital Juice, collapsible green and blue screen.
