totally agree with above - the Jag has a bung on the side, you can't empty all the dirty water from the gate valve and its a faff taking the bung off and leaning the machine over to empty all the water from the bung during a job, this means the water level is always higher when you are during a job and if using anything above 200 psi the dirty tank fills quick and foam or water ingress into the vac ports will happen sooner rather than later
the Jag was flawed from day one - this has lead Solutions to speed up producing their own machine, if you want a machine from Nick look at his machine made by him, not the Jag - Nick does do a maintenance plan scheme with his a new machine which is good for newbies. The Jag's problems i believe were ironed out by Nick at Solutions, not the US manufacturer so do you want a machine that needs upgrades done in the UK just to make it useable here?
as regards the Airflex, i have one now (the Turbo) after 4 years working with the Scorpion which was a reliable version of the Jag. I much prefer working with the Airflex, it wheels better, is manufactured much better and can empty all dirty water from the gate valve. It has proper switches, big back air wheels and it also looks better which isnt a major factor but is a consideration.
the Enforcer is also a great machine with very good reports although i havent used one
