Hi James, i have a Recoil, which is the earlier version pf the Scorpion.
It has been upgraded, apart from the pump, mine has the 350 psi version, but find it ample.
Previously had a CFR 500 Perfect heat, which did a reasonable job, but found the reliabillity to be some what lacking.
I kept the CFR handtools.
With the Recoil, i find drying is as good or even better than the CFR, have upgraded my hose and wand to 2" bore,
the vacuum is awesome for a portable, compared to all previous machines owned, Alltech, etc
With 2" hose can run at 100' without any loss, read some of Ken Wainwright posts regarding this.
I fill machine with hot water, but happy also to use cold for rinsing, also have an inline heater when req.
So for me there are only pro's and no cons.
I think the cost is reasonable compared to other 2 vac machines, and the newer model Scorpion will be on my next purchase list.
