I went to an orthodontist and asked for some of the latex bands that are used for braces. I asked for some with a diameter of approx. 3/8 of an inch. They just gave me an entire small bag of about 100 of them. They were not all identical, so I looked for any that looked to be cut a little thicker (& therefore stronger I hoped). It's a little tricky to replace the belt, but there are videos on youtube showing exactly how to do it. I have 2 players that needed new bands, and those latex ones from the orthodontist worked perfectly! (And they were free!!)
