Hi there - from the UK

Welcome to RALF. AL priority is clearly the best and currently has the best chance of staying in front with future threats. BUT...............it depends on what threats (LIDAR's) you face (and expect to face in the future). If your only threats are older fixed pulse rate guns, there are a number of bargains to be had, used, from people who are upgrading to ALP's.
