do you think there is that much of a difference in actual machine work between a Seiko and a Rolex?
I Should add to that thought... for someone that does not have the experience and skill to tell the difference between the two in use - the added cost up front would be nothing more than added cost. For someone that understands what they are working with, the difference in price is small. In addition, someone with a skill set that allows them to use either brush to their fullest capabilities, they are gonna pull off the work with whichever brush they are using.
That's why I'm asking the question Dave, I don't know. I'm not asking if one is a better tool, I'm asking if they actually have twice the amount of cost in the 770 to justify doubling the price or if they inflating the price to match it's standing to the 270. It's been done before by other companies with no other justification other than they didn't want the price to reflect the quality?.. not sure that's the word I'm looking for.
