You can find some good prices on complete light systems or separate ballasts here. It would be worth paying for a digital ballast system, or just ballast if you want to purchase separates, so you could use a MH for veg and an HPS for flower.

not even ebay has better deals... $500 for 1000w HPS seems the way to go
I could easily make weaker wattage work with some lst and supercropping. I'm going to research some science and look at other ways to get superior light sources
