To spray or roll/brush your paint?

[Ryan Beckland]

This is my first post. I just bought my first property and it needs a bit of paint before we can put her on the rental market. I've always applied paint the old fashioned way - with a rolller and brush. But I'm thinking of buying one of those paint sprayers. Anyone have any experience? I'v hear they use a lot of paint and that the overspray can be bad. I'm looking at both the pneumatic type and the airless electric type. Any info will help. Thanks.
