I'm a member of a few air rifle facebook groups. one of the really popular groups is the "air guns/rifles for sale UK" one, but the group owner is a neo-nazi psychopath so I left the group (i am all for hunting, just not shooting at foxes with air rifles and then posing the dead foxes in 'humorous' postures.. (and admitting that 80% of the foxes you shoot actually run away wounded..)). My favourite group is the local 'air rifles/pistols gloucestershire/worcestershire/herefordshire'. We've got members from all over
.. and there are air bottles for sale on an almost daily basis on these groups.
I was always happy with a stirrup pump personally - I had a Hills one, which made light work of it, but then I'm a 6'2" fat git, so I can put my back in to it
thanks for suggestions above, but thrifty mikey is getting me out of trouble and he will even deliver ,though I'll keep watching the forums for a 300bar bottle
