i know the seller and has always given me a products and stands behind them. ive asked for a bel rx65 rd unit which would be perfect for a lp-905 but im worried about future problems and parts i may need??? so i was thinking of getting the escort zr3 laser shifter? same unit but has a central hub and plugs into a passport x50 rd unit-not a bel unit so it will be a seperate unit working from the radar. but i think it will be worth it, dan
