In terms of standard compressors... with the tobi, you're limited to the Pari Pro Neb Ultra or the Devilbiss Pulmoaid -- the pari is much more compact than the devillbiss, which is what we use for our every day compressor. Our old Pari Proneb Ultra is not working, but I love the compactness for travel, so we're probably going to pick up another one.
Otherwise, ask your doctor about the eflow.
