Started out with a Hill MK3 on a Gamo Urban. Destroyed the Urban attempting to install an Altaros regulator. "Went Big" and ordered a Brocock Commander because I really enjoyed plinking with air rifles and the quiet report as compared to say shooting .22 LR, 90 cu-in Ninja CF tank with EZ Valve, and an Air Force E-Pump which self-detonated in about a month. "Went Big" again after a two month fiasco with Air Force to get a refund and ordered a Daystate LC-110. Ended up giving away the Hill MK3 to a member here. Picked up a Concept Lite from a member here for my kiddos, found out I liked it better than the Commander, and sold it off to a member here.
I hated hand pumping. It was uncomfortable and by the time I was done pumping the heart rate and sweating made me often going "Do I really want to shoot, only to have to pump again?"
Unlimited air makes the hobby WAY more fun. ~10 minutes to refill my 90cu-in tank and I'm back out plinking. I'm happy with my right-sized setup -- LC-110, 90cu-in Ninja Tank w/EZ Valve, and Brocock Concept Lite. Just right to enjoy the hobby and plinking without any hassle.
For me, I found myself pumping more than I was shooting. It made the hobby misreable as compared to the current state with a compressor.
