Did you consider this as one of your options? You can go dual 150 or dual 250. Comes with LED moonlights.

This costs less than the 2 Aquamedics and possibly the IceCap pendant ballast combo as well.

*EDIT*
Oops, I misread. I thought you were considering dual 150 or 250 pendants, not a single pendant. Ignore this post then.
