Ugh, I've had some rough luck on kijiji as of late, got scooped on a Space Duel on my way to go see it, couldn't make a deal a with a jerkbag over a Simpsons, and lost out on a pair of Nintendo Cabs in wicked shape that were $100 Canadian each.
I hate Kijiji, But it's the best place to find full cabs locally.
For parts and stuff I go to vendors websites, KLOV, and here on the BYOAC.
