I think you are wrong Richie.
The posters have all been pretty matter of fact and simply gave their personal reasons for doing what they do with virtually none of the digs that might have been made.
If I have old tools which sit comfortably in my hand, or enable me to achieve better results than " super duper "new, or bigger tools I am unlikely to change.
Ironically, much of what is posted as GOOD reasons to use a T/M are seen by others as GOOD reasons to use portables. C'est la vie !
Cost will always be a factor, for many.................it's frequently posted that you can buy a T/M for around £5 k, but, you need a MUCH BIGGER VEHICLE which could add £12 k to the outlay and much more.
I and a few others have mastered the use of the microvan with the huge benefits available from doing so, eg, access, parking, running costs and about 50% or more saving on set up costs.
I bought a little Suzuki 1300 microvan for just over £5k and it can house a Triple vac / 500 psi portable, 50 feet or more hose, rotary with pads/brushes, upright vacuum, Puzzi and a lot more.
I can go along narrow paths, park in tiny areas, and get around 60 mpg, etc
If I was setting up and had around £40k and 30 years younger I might see things differently.
