I have a 26' and a 10' they are both solid, good quality. The 10' pulls hard if its not balanced just right. I recommend a higher ceiling if you can get it, I am 5'12" and it has a 6' ceiling, always feels like I have to duck. You may want to look for a 12' with a double axle, it will pull allot easier.
I have always managed to find used ones -just be patient.
