LOL depends on how much you want to spend/what plants you want to grow. Will you have co2? Will you be dosing ferts? Or is it just setup and let it do its own thing? Either way, I would suggest 3-4 NO bubls... they're cheaper, more available, and you can get a ballast at a hardware shop and set them up yourself. Or get 2 Coralife E-Z Ballast kits for ~$50 each here
If you need higher intensity bulbs (>40W) you need to go PC or VHO route. Once again DIY is much cheaper, but Coralife Aqualights are pretty good price too.
