My binder came from MORF today. Its is a homemade one, so two large strips of elactic sewn together with a thin strip of elastic and about eight eyes and hooks.
Admittedly I had to spend half an hour resewing the elastic together but it is worth it - any excuse to practice. I forgot how good it feels to drive without the seatbelt being a matter of irritation.
All in all I am very happy to have my first binder!
