Don't get a NEO. Get an eclipse or comparable Badger model. I prefer my eclipse gravity feed over the siphon - and it comes with a cup cover.
Also, cleaning shouldn't be a chore - spray cleaner through after painting, swab, and you should be good. Spray cleaner until no color is evident. You can tear down and clean, but that's not necessary after every change.
I find, with the Iwata, thinner is better. Tamiya paints go in 1 part paint, 1 part thinner. Maybe a little more paint, but that's where I start with most ratios.
Once you get in a groove, hopefully, you will find yourself spraying everything - it just gives a better finish and faster drying than hand painting or rattle cans.
