Hello! I'm currently running the chess club at the University of Oregon and we're considering buying new equipment. I'm not entirely certain what kind of clocks I should get.
Currently I'm deciding between the DGT North American and the ZMF-II Digital Chess Timer. Currently our club has four DGT clocks, but I've heard from some people that they prefer the ZMF clocks. Does anyone have any suggestions?
