Hydromist also manufacture (or did) the President which is 2x3 stage and 100psi. Some of you may be familiar with it as the "badge engineered" Chemspec Hydro 2000. A colleague had one of these, but found it a bit temperamental. He also had problems with the vac tank splitting. Apparently happened to others too. Something to do with the colour (dark blue) Doesn't happen on other colours apparently.
As you're new to the industry Borg, I'd go along with the others here and advise looking at the Prochem range and add Alltec to the list too. They both offer a comprehensive range of machines.
Safe and happy cleaning:)
