I just got this unit in tuesday and i am super pleased. i am going from 4x65w pc to 2x250 mh and 4x65 actinic pcs and moonlights. the fixture is well built and has pretty good aluminum reflecters on it. it was shipped and packed very well. http://www.aquatraders.com/48-760w-metal-h...ic-ballast.aspx for 359$ with shipping and all bulbs included i think the unit is awesome for those who are budget concerned. i did a ton of research on this fixture and believe it is a good investment. worse case scenario the cheaper ballast go bad and i can replace them both for half of the price of getting almost any other fixture. Let me know if you guys have any questions. i will let you know if anything goes wrong in its first few months of operation. After taking the glass off the top of my tank and adding the fixture my tank temp went up about 2 degrees so i am probably going to be looking for a small clip on electric fan for the side of my tank.
