I also got my gymmie's beam from ebay. Made by a gym coach in NY and it has the covering of the beams in the gym, so it doesnt' feel different if she practices at home. We got it over 3 yrs ago, so I don't remember the seller's name. It is 8' long and does not fold, but very easy to stand up in a corner. It has certainly held up well with all the practice she's done on it.
This seller also has several sayings you can pick from and he puts it on the side of the beam.
