I'm currently using the thin (half an inch) leatherette one that came with with my Yashica when I bought it, but I was looking for a better quality replacement. I have seen those straps made for Rollei TLR with the metal alligator grip, but I'm not sure if they will fit in the metal eyelet on the side, just above the pin in which they lock. Anybody had a go at them? Otherwise is there any modern model that is worth looking at?
