The Eclipse HP-CS or the Evolution 2in1?
That's a hard question as both are excellent airbrushes & both would be more than capable of doing what you are looking for. The Evolution obviously comes with an extra needle/nozzle set & paint cup that the HP-CS doesn't & it also comes in a sturdy plastic storage case as opposed to the HP-CS's foam lined card & acetate box. The Evolution also has more "expandability" available down the line with a choice of 4 needle/nozzle sets & various paint cups - the HP-CS has a fixed paint cup, but it does have optional 0.5mm needle, nozzle & nozzle cap available for it.
Parts for the Evolution should be slightly cheaper than the Eclipse, but the Eclipse parts seem to be slightly tougher, so it works out six one, half a dozen the other.
If you do plump for the Evolution 2in1, for all the price difference you would be as well to go with the Evolution Silverline 2in1 - It does away with the standard Evolution's rubber grip rings on the centre body (which can be prone to deterioration from solvent) & you also get "Paint Volume Control" on the handle, which is a needle travel limiter that allows you to limit the amount of paint going through the airbrush (it can be handy for repeatability).
