I agree whole heartedly. That's why I am a self-employed electrical contractor.
If a potential buyer actually thinks that there is an MSRP for used saws, then they're stupid. I'm pretty sure EVERYBODY knows the guy is referring to MSRP of a brand new saw. The seller is simply letting people know they can buy a used saw for much less. Hey, that's why I bought a used saw, because I didn't want to spend MSRP on a new one. On the other hand, he doesn't say it specificly that the MSRP is for a new saw, and he probably should. I do think he should say something to the effect of "Why pay retail of $838 for a new saw when you can buy a properly and well maintained used saw for much less." Then everything would be in the clear, as it should be.
Am I contradicting myself?
In his eyes, and obviously HD's eyes, the seller IS a qualified technician. He was obviously trusted to set up the saws properly for the next person renting the saw. I'm not saying a certified Dolmar tech, if there is such a thing, wouldn't be a more qualified technician, but it doesn't take a whole lot of skills to keep the saws "THROUGHOUGHLY CHECKED, CLEANED, OILED, LUBED AND GASED."
That's what I say. Good for him.
