Have to pay out of pocket for a machine -- here are a few I've looked at, any thoughts, recommendations, experience?
Don't use the bipap feature, love reporting features and ease of changing settings [don't like to use ramp, etc]

S9 Autoset with H5i Humidifier and Climateline Tube
AirSense 10 AutoSet with Humidifier and Climateline
REMstar Auto CPAP with Humidifier and Heated Tube
If you don't need bilevel therapy for comfort or treatment an Auto CPAP makes sense. All the ones you listed are excellent choices and give full efficacy data. Remstar Auto (560) is most like your old unit, with humidifier as a component rather than integral. The much loved Resmed Airsense Autoset is integrated and includes a tattletale modem (useless to you). The S9 is the discontinued model of the Airsense 10 Autoset, but still a fine unit.
