Just bought a battery powered (9v) CO alarm for ~$20. It shows the various places where alarms can go, starting near the water heater & furnance, then the main floor, then near sleeping quarters. Then there are words about recommending them be close to sleeping quarters, and having one on every floor. Obviously they'd like to sell you 3, not just 1. Living in a 2-story ranch, it is my thought to put the detector in the laundry room, close to the source of possible CO leaks. Thoughts?
