I too am at a loss - my InnospireGo gave up the ghost last week, my Pari Big Green Machine is 1500 miles away, and I need a new portable. I hoped for a handheld, but not interested in spending hundreds again so I ordered, for the third time, a DeVilbiss Traveler from Just Nebulizers for under $100. Don't worry, the first two didn't break, they were "borrowed" by my daughters, who are still using them (my grandson will not tolerate the sound of the big Pari.) I figure if a six year old can't break it, neither can I.

None of the cheaper mist inhalers can be adequately sterilized - their recommendations for peroxide soaks just don't cut it with MAC or Pseudomonas.
