I like PC fixtures, more bang for the buck. For your 30G tank you could go with one 65 watt PC fixture, which would give you a little over 2WPG.

96 watts of PC lighting in a 30G tank will give you enough light to grow almost any plant that you want. I also have heard bad reviews on the Dr. Foster & smiths light fixture, I would stick with Coralife or another good brand.
