Best HPS under 250.

Was wondering what you guys would recommend for an hps under 250. Including balast. I found a nice 1000w hortiflux but I can't find a good balast to vent with it. I plan to just run 1k watts.

What would you recommend?

If you want 1k:http://www.amazon.com/gp/product/B004DEBD0A/ref=oh_o04_s00_i00_details
It's not under $250 but its close. Hope that helps
