You might be surprised, but Gammill is just a name of a brand. There are other machines out there that cost as much or more the a Gammill. Just because someone doesn't own a Gammill doesn't mean that they aren't just as invested in their business as you imply. If they are competent with their machine they are every bit as good as the next person. It's more important to be good with the machine you own than the name on it. It still takes the same amount of time to do the same thing with any brand of machine, and as such deserves the same fees.
