the price for a new lightbar is approx. $2000.For spraying it is well worth it.As far as as the price for the pf3000 pro the only advice i can give you is to call ag leader @515-232-5363.Good luck.Oh and by the way if you do use a light bar on your ag leader,DO NOT use WAAS as your satillite provider , use omnisttar or racal.
