The Bololo is a top brand used by many on this site. It can be purchased online. Rinsed neb cups and the Aerobika can go in to be sterized and dried. When I was looking around, not all bottle sterizers have the drying function so if you do go with a different brand I was suggest you get one which also dries as you can leave your equipment in it until ready to use. I believe Monohan which makes the Pari cups and Aerobika list a bottle sanitizer as a cleaning/sterilizing method so safe to use without warping like the microwave issue you had.
