High initial investment comes with anything fun
Longrun though, doing the math between paintball vs airsoft - as far as supplies (batteries, bb's, etc) goes vs paintball - airsoft seems cheaper. Plus you get more realism. So, seems perfect to me.
I don't plan (well, not right now anyway) to import any guns myself - As long as I know I can purchase ones already in Canada that are not "cansoft" looking.
I'll look/ask around for Amos tonight - Do you by chance know if he is an employee/owner of extreme tact? Or is he just a regular?
