I have read a number of previous post about this sprayer and you either love it or hate it, because of its ability to spray your neighbors field. I feel like im missing something though. I am looking at two (3400 & 3200) at different dealers and you have the ability to not use the air and use conventional nozzles (only have called about the 3400)...why would this still be a bad sprayer? Seems they are going cheap compared to similar sized summers....what am i missing? you can use the air for fungicides/pest and switch to conventional for herbicide. there is a 3200 and 3400 does anyone know what the difference is between the two?
