The nice thing about metal halides is that when you go to replace them you are replacing 3 or 4 (in a tank the size of khaos tank). And I really think you'll get a good year out of some decent MH with a decent ballast. If you go VHO you'll be replacing a lot more bulbs (maybe not so much the cost factor but the pain in the ars factor) and probably only getting about 8 or 9 months out of them.
