Need recommendations on Compressor/Nebulizer for Travel

Can anyone recommend, or share their experiences using a travel-sized compressor/nebulizer? I've got a ProNeb for home use, but I really need something I can take with me in the car, to work, or on a trip. Thanks.

I also have a Pari Trek and love it
Others I have used in the past and also found good were the pulmoaide traveller - bigger than the pari trek but less parts and easier to operate
and the mabi mist ultrasonic handheld neubulizer - this one actually fits in the palm of your hand and it remarkably quick for being so compact. both of these are rechargeable and come with a car adapter and travel case.
I am not sure where you are located or what your health insurance situation is but I would be willing to sell either of those travel compressors to you - the pulmoaide is in excellent condition and the mabi mist was only used for 2 weekends.
