Hi Guys
There will always be differing opinions when it comes to machines, lets face it there is only so much power that can come out of a socket and that has to be split between, vac, water pressure and heat, you pays your money, you makes your choice.
I believe , especially for a newbie that heat is really important and I would not recommend a machine without it, for a new starter.
Once someone has a wider understanding of what makes a good clean, then they may decide to sacrifice heat for vac or visa versa or they may just buy a truckmount, but that's another can of worms.

Another issue is looks, I have found custies like dials, Extacta, Alltec, they probably perceive as being high tech.
In my view both the Ninja and Scorpion and to a lesser extent Prochem look like plastic buckets but again that is a matter of personal choice.
Cheers
Doug
