I've been interested in getting the 30"x60" softbox with grid from Paul Bluff. I currently use an Elinchrom Ranger RX with the 39" Deep Octa, but was interested in the PB softboxes because there are no grids for the Octa. Plus, they're a lot cheaper than the Elinchrom ones. Anyone use softboxes from Paul Bluff on here? How's the quality?
