I have 2, and fire them a couple of times per week at home.
a Weihrauch HW97K in .177, and a Röhm Twinmaster combat, which is basically a double-action revolver on C02..
The Weihrauch is stunningly accurate.. I'm waiting for the spring to break, so I can get her tuned with a new spring, pistons, and a good lube job. I never had the courage to take her apart myself.
The Röhm is for what we call 'plinking'. Shooting stuff like soda cans, playmobil etc. to pieces.
I'm saving up to buy my first PCP, which will be a Daystate or a Theoben in .22
If you manage to shoot accurate with a springed airgun, everything else is a breeze. I shot a lot of fire arms, but learning to group the Weihrauch was the hardest of them all..
edit
In my Country people are very nervous about firearms, but our airgun laws are very liberal. There are no limits to power, in contrary to surrounding country's like Germany and the UK.
Airguns like the 'Beaumont' are available up to .50, 325 grain and deliver waaaay over 500 joules. That's more then a .22 delivers. Hunting with airguns is forbidden though, and they can only be used on private propertie or the shooting range. Most popular calibers here are the .177 and the .22. Popular springers are Weihrauch and Diana (German) and popular PCP's are AA, Weihrauch, BSA, Daystate, Theoben, Evanix, FX ..
