I was using a baseball bat bag to haul around my light stands, umbrellas, and all my accessories. It was cheap ($39), had wheels, and easily available for purchase at many local stores. The only thing it couldn't carry was my
Avenger A475B Boom Stand. The boom stand was too tall for the bag. Other than that it worked great!
The only downside was the bottom of the bag wasn't durable enough. I've been through two in two years. Not too bad but I found a better solution.
This is a
Travel Cover for golf bags. Academy sells then for $79. This bag has super padding, reinforced bottom, wheels, and PLENTY of storage space for all my light stands.
