I had a scorpion with tanks, worked very well, bit of a hassle with leccy cables,
but not too bad, had an inline heater, did excellent job.
Now have a truckmount, easier having no cables, plenty of heat, was it better than tm,
only just, used both today on same job, no difference in quality of work or dryness.
However i have only got an entry level tm, so it depends what you are comparing
it against.
Scorpion is 300psi tm is 800psi, often i run tm on 3/4 throttle, and have psi down to 200psi,
just depends what you are comparing against again.
Cost wise again are you comparing new scorp against second hand tm or vice versa.
Lots of different comparisons.
my opinion.
