Which gun would you buy?

Hi

Just joined and I think I want an air gun just to shot in the garden really. Ideally, I'd want to be able to shoot multiple shots. I watched a video on the FX Dreamline Compact which looked amazing. So I don't want to become obsessed with with guns but I want something cool to play with. Is there anywhere I can go to try out some different types of air guns before buying one?

I'm in liverpool. And finally where is a good place to even buy guns?

How about

Or there is a shop called Taskers Tackle in Liverpool and they have guns, but don't know if they have lots of types of guns or if I try them there.

Any info on what types of guns I should consider? I don't really have a budget, but dont want to spend loads.
