Based on what you're saying, eg-sinz, I think your best bet is to actually come out to a game at Flagraiders in Kitchener. You can pretty easily find yourself a rental for the day. It will also given you an opportunity to get AV'd, ask questions in person, AND take a look at the many guns available.
You really want to see airsoft in person before deciding not to play or what not to get.
You might even be able to carpool with some of the London players.
