The local Kioti dealer sells them and I've looked at them quite often. They are built well, have a good reputation for being a quality sprayer. One thing you might want to consider is remote controls for your booms, especially if you will be using it with a cab tractor.
Another good sprayer made here in Pa is the PD Zimmerman sprayers (Think they are now called Crop Care). I bought a used unit and am very pleased with it.
