I personally started out with a cheap one that I got off some ad on Instagram, think it was $40 shipped with the foam cannon and a wand with no extension (basically it is the trigger to a quick disconnect). It worked but was way more of a pain than it was helpful. It always started to leak about half way though washing my truck. I had replaced one of the seals in it about 3 times and finally got fed up with it. I tossed it in the bottom of my box and ordered a Chemical Guys one. Total world of difference, I have no leaks and it has been nothing but pleasant using it. The thing to also look at is you usually get about $20-30 worth of soap when you buy from CG, plus they did just have a 30% off sale and they are still running $2.99 flat rate shipping. Basically what I am saying is you can get one from CG for fairly cheap if you look for the right deals and take into account that you get soap with it.
