Here’s a recreational diver’s point of view about servicing regs. A diver that is a city person, with an office job that does not DIY anything. Second stages are easy. First stages are much more complicated. The specialized tools involved is a lot more than what people are suggesting.
This is about 25% accurate - 2nd stage being very easy without specialized tools.
I used to think 1st stage is "much more complicated" until I give it a try. It is actually surprising do-able as well. You will need specialized tools, but not HOG only tools, just general scuba tools. they can be had for cheaper than the labor you cost for one service.
I mean doing service service or not is not the key here. Having the option to do it when you want is what most of us here prefer.
