Changing subtopics last year I upgraded from the Broncolor Hazylight (large studio footprint and heavy somewhat dangerous weighted British Broncolor Boom) to the Octobox 150. Now I simply cannot live without it! I picked mine up mint condition used from Adorama in NYC. Price was $250 so a very fair price IMO. For my uses I needed a slightly softer diffusion on the front, so I bought the Octobox 150 Supplemental Diffuser as well. Easily movable, smaller studio footprint, like a movable adjustable window light. I use this with GREAT regularity for all sorts of uses, I'm in love!

Another excellent tutorial that takes you through in a very thorough manner, the wonderful Broncolor Octobox 150.
