Richard,
GREAT POST! Yep, that is exactly the type of stuff I need. I know the
802.11b repeaters I am looking at are going to be about $1200 for the
pair. How much do you think the routers will run me?

And good catch on the 911 issues. That can be a real mess to get
straightened out if not caught right away!
