Hand pump? I just serviced and resealed my Hill pump for the first time which is about 20yrs old. Back to new again for the next 20yrs. Keeps me fit and healthy. As long as you are 10 stone or over and not a complete wimp, it will be fine.
Bottles are great but need refilling if you do any volume of shooting. NO experience of the chinese pumps but I understand they work ok on small reservoirs but can overheat quick on filling larger bottles. Hill do a very good item but it is about a grand to buy.
My Hill pump is well made but a couple of years back I upgraded the nephew to a PCP and rather than him wreck my pump or constantly call me over to charge his gun, I just got him a cheapo chinese hand pump. Was about £30 from memory. Seems to be doing fine still and will have pumped that gun up many dozens of times by now so they can be purchased with a degree of confidence.
