I use a regular wall mounted (has a push pin like hanger) laser level with a built in stud finder. Its blasts one wall and the other corners about 8" in at 20', I then mark those corners with painters tape and go around the room, you'll have all at the same height. (Tape just in the corners for markers, not tape all around the room)
