that looks exactly like mine!! I got my roller from a local company that makes conveyor systems. It was on old one so I only paid $18 dollars for it. I then went to Home Chepo and bought a little flat steel and cut two brackets like that with a hack saw. I have been so happy with and I cant believe that people will pay $300 for some of them. Im sure they are good quality but I have had mine for over a year on my two lazers and havent had a problem but sure have gotten some compliments.
