I'm in my 40's, got my first airgun at 10, or 11. Still have it, and my 10 year old loves it now too. I lean towards springers, and have 4 or 5. The fun never wears out, and some winters I have set up a range in the basement. Awesome, quiet, cheap, and recoil-less shooting fun! It got boring with my fav. (I can knock the eraser off a pencil consistently in my 30 ft range), so I acquired a pistol...being the world's worst shot with a handgun, it's certainly cheap n' easy to hone the skills.
My Dad bought a side lever .22cal a couple summers ago at a flea market near South Hampton/Port Elgin. It's made in china, and sub 500fps. It's a hoot to shoot! I have a BAM .22cal springer too(break barrel), and it's also a hoot.
Air rifles don't get the same attention as powder burners but they should. Shooting principles remain the same, and ammo is as cheap as can be.
Westport?
If you're only curious, I'll loan you a springer. I'm about an hour away (half hour west of Perth). I bought my pistol in Perth from hxxp://scopesandammo.com/
