I have Yong heng compressor for a few years now and its absolutely brilliant. I pump the rifle up regular and change the little filter every 3 or 4 fills so no moisture enters the rifle. Hand pumps are a pain in the you know what's and those dive cylinder are limited enough with high pressure fills especially if your rifle fills 250 bar or over and you have to travel long distance to fill them. If you decide to get a pump like that only fill your rifle and not a dive cylinder and change the oil often with oil recommend. Also start the pump before pressuring the the system if that makes sense. Just prepare to fork out more money for pellets as you will find your self shooting more with your own supply of air to hand. I can't comment on the pump in your post but just the pump I have my self, but they look similar enough.
