I'm looking to pick up a foldable softbox, ideally something in the 30"-36" range. The first one that came to mind was the Wescott RapidBox. They have a 36" version in AB mount (it needs to be AB/Balcar mount) but it doens't have a grid. Plus some reviews have suggested that RapidBox isn't that well built (some have said it is well built though), so I need some more info. Any recommendations would be greatly appreciated.

If money is a consideration how about the 35" Alienbee Octabox, which has a grid available??
