Not trying to high-jack this thread, but has anyone tried the new Millenium M-1 climber? I'm hoping to get a new climber this year and want either the Summit Viper or LW Sit and Climb, but I have seen that Millenium now has a climber and it looks appealing. It has the same seat as their lock-on (comfortable) and it has a level-as-you-climb adjustment.
