Mark a good and valid piont,and it really does come down to what your more comfortable with, personally i love my alltec machine,and the service i get from them, and mine has one lead, i prefer to wait for the water to get to temp,then i can give a even clean, but i will be getting a recoil, the idea of not having to take the machine out of the van(most times) appeals to me, the pump size/flow rate, and the vac power combined with the booster box mean that i coud run 200 ft o hose if needed.
Once again i am not having a pop at any one,calm down girls for gods sake
