Does anyone have any ideas of where to get one of these?

http://www.backpackinglight.com/cgi-..._rod_case.html

I have searched the web with no luck most sites just say out of stock I have thought about using a cardboard document tube but once it gets damp it's useless....maybe wrapped in clear tape? Plastic tubes for golf clubs may work I seen an article somewhere....but what would you use for end caps?

I am curious what others use to carry their rod into the backcountry in. Any ideas would be greatly appreciated the factory rod/reel case weighs over a pound and doesn't fit inside my pack. I can't see carrying a pound of extra weight if I don't need to. Without the rod case and 2 nights worth of food/gear....in colder weather I am at 28 pounds.

Again any ideas would be greatly appreciated.
