I've never met an airbrush I didn't like.... except aztec's..... :-) :-) :-) ....... As for easy cleaning.... you can't get easier than a top feeder..... any brand.....
I use the following, and are my honest opinions of each.
Iwata HP-B.... excellent for fine spraying.... .2 tip, don't think they get any smaller than that, but I certainly don't expect it to do anything other than very fine work. Easy to clean. Parts are expensive, and usually not found at your average hobby shop. Tips run about 30 bucks, needles around 12. Has excellent balance and feel to it.
Paasche VSR90.... a good general all round top feeder, works good with all mediums, and has two size tips, fine and large, and two size cups, small and large..... fairly easy to clean.... Parts are cheap, and available most places. Tips and needles average around 5 bucks each. Has good balance and heffty feel, and can feel heavy if you are doing a prolonged spraying session. Also the changeable top cup sizes have a habit of coming lose if not poperly seated.
Badger 150..... the old standard.... first airbrush I ever bought, used the original for 30 years, never had a problem or major repair. Passed it on to a fellow modeller when I bought a new one this year, and the only reason I bought a new one, was an unbelievable price at a store closing. Comes with three head sizes, and once you learn which size to use for the needed job, will cover most modelling needs. Newer models come with the crown end piece allowing closer working distance. (use to be a separate part to buy). Parts are readly available, and affordable, tips are around 5 bucks, needles about 5 bucks, and a complete new head assembly about 15 bucks. Being a bottom feeder, they are a little harder to clean, but once you master the cleaning, they take only a few minutes to clean. Has a good balance and feel, and can order a brass (heavier rear barrel for better balance) Can be set for single action by simply adjusting small screw on top by trigger. Can use color cups and larger bottles. Both need to be properly seated for tight seal, and so the don't leak or fall out.
My personal favorite......
My badger 100G...... just about anythng I can do with my Iwata HP-B I can do with this brush, PLUS change the head and needle in the middle of a spraying session from a fine to a medium, or a medium to a fine (Of course I have to dump the color cup first)
Uses the same heads, tips, needles as my 150, so cost wise and spare parts are well covered. Super easy to clean, well balance.
