Ya I am thinking about getting a pressure pump too. Home depot sell them for about 15$. Only application I see that would be useful for me would be to spray carpet/fabric cleaner for doing interior. I will have to do a few with the spray bottle and see if it bothers me enough to change to the pressure sprayer. My big issue with it is that it's kinda bulky and I already have a ton of stuff that takes a lot of room. When I start in a few days I won't have a van, I will be using a car to carry all of that so any additionnal bulky item is something I am trying to avoid. Once business picks up and I get a van, then I won't mind at all and might actually build a low pressure system like the one Garry Dean just presented in his latest video. That's pretty neat and very inexpensive if you have a van where you can make a permanent setup.
