Where to buy Airsoft online in Ireland and whats a good brand?

I want to buy an airsoft pistol and possibly try out some skirmishing. I'm totally new to the sport, but have a fair idea of what I want. My ideal pistol would be an M1911 or variant, preferably in full metal. I am unsure of whether to get one that uses gas capsules or the stuff in a can, Basically I'm just looking for advice on what to look out for when choosing a gun, and where I can get best value for my money, both with my initial purchase, and for the long term use of the gun. I'm based in cork city, so if anyone knows any shops in my locality, that would also be appreciated. Thanks in advance.
