Yep, that looks good. At around a thousand dollars you can get the base package, which is nice, if still not cheap... of course, making a backdrop that's the same size as ours (roughly 13x25 feet) would cost quite a bit more.
The other thing is shadows - when making wide shots, it's actually a GOOD thing to have the talent cast a shadow on the greenscreen - when properly lit and keyed, it helps to make the shot believable. There's no shadows at all (AFAIK) when using reflectmedia.
Anyway, it's an option worth considering, and for many situations, it might be the best there is.
