Thanks, I called and talked to Mark and his pricing was better. I went ahead and ordered one with 375' of 1/2" hose. He says he can squeeze the 400' on there for you but it leaves 0 room so I decided to do a little less and have some slack.
Now to get the backpack sprayers, spreader and all the other little odds and ends like measuring cups, nitrile gloves, etc.
Anybody care to give me some hints on the odds and ends? What sort of things do you find indispensable (or at least really useful) that you wish you'd known about starting out?
