After replacing my three year old, and very dead, batteries I have decided to upgrade my charger to something a little more modern and add a Link 20 Battery monitor.Being the tightwad that I am I was looking on ebay at the link 20's but just don't feel comfortable dealing with someone I can't talk to or see.Can anyone suggest where I can purchase a Link 20 from a reputable company at a reasonable price?Thanks for the help.George S/V Windswept _/)
