User Bastep has a great freebee background lighting preset that I use now. One thing I did was load it up with one of my HDRI files so that it would always point to my HDRI folder when I  use it.

@hborre What I do with low HDRI's that render dark is un-clamp my render light settings and then use the post-FX exposer settings to bump up the light.

Also make sure you have enough diffuse bouces (I use minimum 6) That will put more light into your scene
