What’s the story with paint sprayers?

I have a whole brownstone to paint — lots of freshly spackled and primed walls, and lots of unprimed pine trim. Painter estimates are coming in around $10K, so we’re thinking about painting ourselves.

Are paint sprayers the way to go? Are they much faster than regular rollers? Is the paint applies evenly/smoothly? Also, I see there are lots of different kinds (airless sprayers, high-volume low-pressure, etc.) — which one is best for what use? I would be OK buying a relatively expensive sprayer since we’d still be saving so much money from not paying for a painter.

Thanks for the advice.
