The slide doors i have seen in person were all expensive and cool and took forever to get to work. Weeks months with techs coming back to fine tune them.

I think the swing door option is the way to go. It would never work for me though. I cant use the keyless entry products either. I would have to buy a new door. The one i have goes from (based on season) slamming shut if you let go of the knob to me having to push with all my strength to get it shut enough to get the lock to turn.
