If my work vehicle breaks down, I can take it to my mechanic and explain to him that I'm out of business until I get it back, and he'll fast track it for me. I drive the car a lot, get a lot of servicing done by him, and don't quibble about the extra money, so it works out well for both of us.
If one of my cameras breaks down, I'm out of business, but despite spending a lot of money there on an annual basis for many years, they tell to get in line with the shlubs with their kit cameras. That's crap. If they want to charge me for me for NPS membership, that's fine, just fix my gear in a reasonable time frame.
As for the used equipment, I'm in business for myself, and if I had to spend $6,500 for a camera instead of $2,500 for a used one, etc. times my entire bag of gear, I'd be out of business pretty quickly.
