SoulAssassin,
The HP-CS is the Eclipse model I have and it's really well suited for painting models (Both RC and smaller scales). The body design is a dual action, gravity feed ( 1/3 oz. color cup is integrated into the top of the airbrush body, read non-removable) the needle allows a lot of versatility from very fine lines to wide spray coverage.

The other Eclipse models basically have either a smaller (1/16th oz for HP-BS) a removable side mounted color cup on the HP-SBS, or are a syphon feed HP-BCS (has a lift hose) design with a bottle attached to the bottom. All are internal mix and made of high quality easy to disassemble and clean parts. They are also relatively popular so parts are easy to find. Iwata also has a 5 year warranty.

Here's a link to their site page for the Eclipse Series

And this is the product description for the HP-CS from that site.

This multi-purpose, high-paint-flow, high-detail Eclipse Series airbrush covers a wide range of uses. Commonly used to spray premixed or heavier paints, it is well suited for uses demanding precise control of spray when applying moderate-to-large amounts of paint to a variety of surfaces and to various-sized areas. This Eclipse Series brush has established a new benchmark for excellence in an all-purpose airbrush.

· Gravity-feed airbrush features a unique 0.35-mm needle and nozzle combination for fine-detail spraying, but with high-paint-flow capacity

· Generous 1/3 oz. sized cup is designed with a new funnel shape, which makes for easy clean up and more efficient paint flow

· Automotive artists, fine artists and students will appreciate how well the Eclipse CS sprays heavier acrylics and Medea Textile Colors, while maintaining high-detail spray characteristics


I hope this helps at least a little. I don't believe you can wrong with that brush. But that's just my humble opinion, because it works well for me and the techniques I employ in my model making.

Best of Luck!
