Sorry if I sound like a walking ad for the company, but I figure a lot of you are considering getting new lighting and studio gear either now or soon for Christmas or Chanukah...
Calumet has nice sale prices on some of their most popular items through the end of the year:

On the home page, click on the Calumet Sales Flyer button, then the link to studio gear.
Of special interest may be the Travelite kits (and accessories), as well as the LiteLink Radio triggering system...
