wanna see inflated prices, buy a boat!
Buying a porty and some basic tools etc, not too bad, 2-3000 and you have some some quality equipment. That and there is no real "exams" or certifications to take to promote yourself as a "professional". Not like being in construction, building, plumbing, electrical, where there are inspectors to satisfy/pay off
or even a mechanic. Some quality tools for these guys can be several hundred/thousand. Someone said that its not the price of the tool but what the tool can make you. $7-800 for a wand, $3-500 for an uph tool, $20-60K for a TM, or $3-5K for a OP machine.
As for the obsolescence of a 60K TM, it'll be a LOOOOONG TIME before that will happen. The day they start washing clothes by some other method than with a significant amount of water will be the telling point. As far as I know, even these HE machines still use quite a bit of water. That said, I prefer the old tub machines, clothes just don't seem as clean from a HE machine. (reminds me, have to do laundry, I'll just grab some of that SEBO powder and rub it on my clothes and shake it off, follow it up with a wipe from a damp cloth)
There's a place for LM methods, I've used them from time to time, and in one case was able to correct severe wicking of road tar. However there's something about flushing a carpet with water where you KNOW it's clean
