Raven Envisio Plus has developed problems with the touch screen, apparently it got tired of the touchy feely stuff.    I called Sprayer Specialties, where I bought it from and they said buy a new one, including the antennae.   Bugs me to no end to have replace something that cost a lot and is probably only 5 or 6 years old. 

I haven't checked anywhere else, but does anyone repaid these things and quick?    If I have to replace it, what should I get?   I'd like to avoid Raven the second time around.   I'm not one to reward failure, but it does connect to a Raven 450 controller.
