I've gotten Photflex and Chimera softboxes.... I wont ever get another Photoflex though. They use a PVC interior coating that deteriorates. My very old Chimera banks are still going strong.... Photoflex... has yellowed a bit, so I restrict them to monochrome use.
+1 on the chimera softbox, not cheap but it will outlast almost anything else; studio stands, Manfrotto is IMO the best value, works well and relatively cheap, Matthews is very nice as well and better finished, but IMO a bit expensive (at least here in Europe).
Don't forget that in the lighting accessories department, you can built on your own a lot of things with cheap materials, styrofoam, white nylon fabrics, aluminium foil are your best friends.... Though a good softbox an important minimum equipment.
