Hello I also have been using ombré comppressor by advice found on this forum. It’s reliable, not tthat big or heavy and the price is good as well. I even take it with me if I go somewhere. With it I use pari and aeroclipse nebulizers- you can sterilize them, all parts by boiling or in steam bags or alcohol. Pari is compatible with aerobika so you can use both at the same time. Good luck with the choice and I hope you will find something right for your needs.
