I looked at em all, and decided for the money I would build my own and come out way ahead. went with an adjustable to 60psi pump, pvc tubing, good no drip or drain back spray tips, and a good ole 55 gallon drum. works like a champ, sits on a deck I made for it on top of bottom of three point arms, switch on the fender for power, and a diverter valve that changes the setup to a gun sprayer, with a 50 foot retractable hose.
