RIGHT ON. I had to completely rebuild and re-fabricate mine right out of the box it was so cheap & poorly designed imo. Fell to pieces immediately in so many regards I actually took the time to write the company. It works ok now but it isn't even close to the same sprayer I bought.
I have a Hardi Nav1000 sprayer that's pull behind, love it. If they make a 3 point, I sure like Hardi. I think the new Nav1000's have to be $40k though so I would hope they have a budget 3 point type set-up or that probably wouldn't be an option. 3 points of course will be less - all I'd suggest is getting something sturdy built that has at least 200 gallons as long as you have a category 2 or greater hitch. The smallest of my tractors, 60hp can easily handle a 200 gallon 3 point (I do have loader on front & my other medium size one has weights). My 3 point sprayers, have one where I have booms BUT I mounted a boomless nozzle on it as well ($200) so I can use it in tight areas & little spots where I don't wanna mess with booms.
