The airbrush is Iwata, but the compressor is a house brand of Airbrush-depot. It is more powerful than the Passche DA500 that you selected, even though the Badger 100G or the Iwata HP-CS would not need the extra CFM or psi. It is a personal perference between the two options. Both should work well for you.
Airbrush-depot charge for shipping. They also sell their items cheaper on Ebay than the internet store. If interested, you may want to check their Ebay store too.
I got the Iwata HP-CS on sale at Hobby Lobby for about $110 and Harbor Freight had a sale on compressors for $60…I got a great combo for less than $200
