@laneyk I got my first one at NJH and I thought it was about $80? Unfortunately, I melted it using a micro steam bag when sterilizing. I added minutes without adding extra water-big mistake. Allied medical sells the Aeroclipse set which is just a nebulizer. When I went to NJH they wanted me to use the entire Aerobika OPEP with the manometer. This has a built-in flutter mechanism and the manometer measures exhale-for optimum use. After melting it, I purchased another from Allied Medical (can google). I also purchased an OMBRA compressor. I liked the OMBRA since the tubing can be changed along with tiny filters. My first compressor was a cheap rental (few bucks per month), the tubing was not changeable, and it had no filter. Good luck and let me know if you have any additional questions.
