I found some cedar "pants hangers" that were longer than usual on clearance at The Great Indoors in Denver on my move to SF. I only paid $2 and change per hanger. I can't tell you how long they are, but I'm a big guy and they hold up my kilts pretty well.

The Great Indoors is owned by Sears, if memory serves, so if you have a Sears or Sears Grand around you, you might see if they have any on clearance.
