I wouldn't even get a rig at all to begin with. Just go and try playing a few games and see how you like it. New players can run around with tactical maracas (high-caps) or get a few midcaps and stuff them in your pockets or something.
AV'ing can take a while, give it 2 weeks to a month.
Yes, airsoft can be pretty expensive, but only after you JUST start getting into it. It is the startup cost that is pricey once you decide this is a worthwhile hobby and investment. Then the price of the gear really starts becoming apparent.
G&G TopTechs are actually compared quite often to higher end brands like VFC. Don't confuse them with Combat Machines which are a good beginner gun, but don't hold up against a VFC.
FYI, kijiji's policy actually bans replica firearms, airsoft included.
