Hello,
After shopping around much, purchased a nighthawk digital for $33 from
wal-mart.
These are expensive and I'm wondering if the best placement would
be high in the hallway near the bedrooms. There are 3 bedrooms that are
occupied.

I put mine in the basement near the floor. Only my water heater or furnace
could make CO, and I would rather find out about it when there was CO in the
basement than when it hit the bedrooms.

No alarms in 5 years.
