MZ,
I have two and I provide the following for your reference.
Iwata Eclipse CS .35mm - Excellent all round AB which I use for small delicate work thru to medium projects. I find it easy to clean/maintain running lacquer thinner thru after each painting session with no issues. I would highly recommend, depending on use, to strip down and clean every week or so using the super lube where nessesary.
Iwata Revolution CR .5mm - Very good for medium to larger paint projects, personally I purchased this as an interim to a minature spary gun to paint primer, top coat and varnish over larger areas. Again, an easy to clean and maintain AB, and I run lacquer thinner through after every paint session with no issues. As with the Eclipse CS a strip down once in a while and lubrication will ensure a very long service life.
Note: I use lacquer thinners as I have an extraction system that vents externally. if you dont use an extraction system, extreme caution must be taken and the use of a respirator with proper filters is a must.
I have run the Eclipse since Dec 16 and used it at least 6-12 times a week, with absoluley no issues and performs the same as when new. The Revolution I only purchased about 2 months ago, but as with the Eclipse, is performing with no issues whats so ever. Both can spary hairline up to about a 30-40mm round spary pattern. The Eclipes can be altered to a .5mm which I couldnt see the point, as I was always going to purchase another AB.
I looked at Paasche, Badger, Aztek and other brands before I got the Eclipse, but felt the quality with the Iwata was superior.
I hope this helps.
