Paasche H... Considering This Purchase

I'm a real AB novice, so bear with me if you've heard this before...

I had an Aztek A4709 that I just sold on eBay, for me I found it to be a little too unreliable. My AB needs are, at this time, very simple I think. I work with small (Z scale) model railroads. A fairly typical AB use for me is to paint individual railroad ties. I do this via a simple mask. Another use is to paint rock formations that I've cast in resin. The rock is generally painted with a solid base coat, then additional shadings are added.

I likely will never need the degee of control of fine spray that many AB users require.

What I do need is a:

1) Relatively fine spray / mist
2) A brush that doesn't have the tendency to spatter
3) A brush that is good with acrylics (I currently use Polly Scale)
4) A brush that is low maintanence, easy cleaning for me is good

I won't be using this new brush all that often, so in some ways the Paasche H seems like a good choice, but I've been told it produces a coarse spray. I know terms like fine, or coarse are subjective unless you can see it in person.

I had one person tell me the Paasche H delivers a spray more coarse than a can of aerosol spray paint. Not knowing how to judge this statement, I'm a bit lost on my next AB purchase.

Any insight appreciated.

Thanks,
John
