Thanks for the reply. I just called GNC and they quoted about $5600 for that sprayer with $300 for shipping.
Gregson-Clark has something close (300' 1/2" hose and manual start) for about $3900. I don't mind spending extra for something if it's worth it but do you think the GNC is $1700 better than the Gregson-Clark? If so, what makes it better?
I'm not asking to start an equipment debate, just honestly want to know what the additional $1700 buys me.
