actually, maybe I could get away with getting an extension for my broken AEA. The top section is stuck and won't move, but the rest is fine
The Mathews baby telescoping extension is good for 4 feet and cheaper than the competition. Have you contacted AEA about repairs or parts?
As I mentioned before, the Manfrotto 12ft. Alu Masters (about $115) are nice, air cushioned, and stack/lock together for convenient carrying.
I also have the B&H Impact 13ft, which is cheap, but likely won't last - their collars are all plastic with brass threaded inserts. Great while they last.
To convert the baby 5/8 light stud I use the B&H Impact CA-102 3/8 Rapid Adapter ($9) to convert to 3/8 threaded stud, which fits those mic clip inserts which I loctite onto the adapter above some washers.
