Compressor #1 and #3 are the SAME compressor sold by the same vendor, TCP Global. One in a combo kit with airbrush and the other compressor alone.
If you go with the Iwata, you should go with the Smart Jet instead of the Sprint Jet. The Smart Jet has the auto turn-off feature that saves the wear and tear of the compressor and makes it quieter.
If you are the adventurous type, here is another option. The compressor looks extremely good on paper with very low price. But I have no information on the seller and the reliability of the compressor they sell. If you buy one from them, let us know how it works out.
