When I was a volunteer assistant in scuba training (late '70's), I remember one evening at the post pool-training dinner with the training staff when the dive shop owner was lamenting over the non-sale of a couple of pallets of black scuba cylinders he had obtained at a super bargain close-out. The lead instructor responded to this with, "No problem, just have the instructors wear black tanks this class. I will bet you that this will sell your tanks." 

The bet was accepted.

So, for the 8 weeks of pool training and the open water weekend, all of the instructors and assistant instructors wore black scuba cylinders.

Within a month of the open water weekend, all of the black tanks had been sold.

The bet was won by the instructor and the dive shop owner gladly paid the wager-incurred debt!

The point is:

Scuba diving students will imitate their instructors choice of equipment. 

So, once you choose to be part of any dive leadership group, you will be expected to use top-of-the-line equipment. If working in a dive shop scenario, it is only courtesy (and sometimes a requirement), that your choice of products reflects items sold by the dive shop franchise. This is in the best interests of you and your students (in general, top-of-the-line is better, more reliable gear, especially with respect to life-support items like regulators) and helps support the livelihood of your employer.
