I started my pcp journey with a hand pump, later bought a tank and was having it filled, then bought my own compressor so I could fill it myself as much and as often as needed. Personally, I'd rather spend my time filling my guns quickly from a tank when I'm shooting, than waiting for 3-10 minutes for one of the battery-operated style compressors to fill my gun so I can shoot again. I like the portability of the tank over dragging a compressor around. If I needed more air for an outing than what one tank could provide, I'd buy a second tank.
I have been using a Yong Heng hardcover model compressor with a second stage filter filled with molecular sieve for the past three years, it has more than met my needs for air in that time period as this same unit or the pressure set model has for many other forum members here. Obviously, everyone has their own needs and preferences and if the 110v/12v units meet the needs of other shooters, I'm happy for them. The main drawback I saw with those units when looking at compressors three years ago was the lack of parts support and service for them. That was then and continues to be a problem with many of the small oilless compressors as they seem to be treated as disposable. Fortunately, you can find repair parts for the Yong Heng through aliexpress.com if you hunt for them.
I won't blow sunshine up anyone's skirt and tell you the YH is perfect, but it does meet the needs of many airgunners around the globe, and it has established a decent following as well. Good luck on your pcp journey, I wish you well on choosing your options.
