is it the same ole guys doing the training on a lot of these courses , looks like the pierce guy is doing the texatherm ...but also does the alltec and others .
I would go for the alltec course over the texatherm , alltec dosn't really have a skewed overall cleaning philosophy , thexathem pushing its mediocre machine and products would ruin theirs .
Solutions would be a grooming process towards selling their questionable methods and lousy machines .
Ashbys course is probably a well rounded ...
Cleansmart do a course free if you buy a machine ? it would probably enough to start with anyway .
