Councours has been around for some time. They have survived though the last exchange problem where many of their competitiors did not. My guess is they are a safe bet, I am not in that industry but know some guys who have worked there (I think my brother in law is there now?) hard to keep track, you tool guys change jobs too often!
If you can get a job in Windsor right now, you are one of the chosen few. Good time to move here though, houses are cheap, cheap, cheap right now. Many forclosure deals out there. BUT if it does not work out at concours you WILL be unemployed.
