Since no one else has mentioned it, $1200 is quite a reasonable starting budget, especially if you already have portions of your kit. A good high quality gun is probably going to run you $600, and a decent sidearm, probably $250-300. That'll leave you about $300 for kit. Which is doable even if you didn't have anything already, though if that were the case it'd be getting alittle tight.
As to whether it's worth it or not. Asking that here doesn't really serve much point, we all wouldn't be here if we didn't think it was. But objectively things are improving, several of the serious manufacturers of airsoft guns have been releasing Canadian legal versions of their guns. I know my group has increased it's membership more in the last six months then it ever has before.
