So i have found a reasonably priced 600w ballast 202$ Canadian, come with reflector ballast and MH and HPS bulbs. Its made by a company in china called WelThink. Has anyone heard of this company or are Chinese balasts reliable? The company specialises in grow lights so it seems ok.
Cut & Pasted from another forum...

My company imported 500 ballasts from Welthink in HangZhou China under an OEM agreement in early 2009, over 50% of the units have been returned in less then 8 months. Problems range from poor quality caps and other internal components burning out to units that completely blow up and start fires. I mean, we have seen units where the fuse is completely blown out of the unit!
Also, Welthink has been less then cooperative when it comes to honoring their warranty. They avoid our calls and emails and try to accuse us of tampering with the units.
Sonny from Welthink in VA eventually sent us out 48 1000W units as replacements (ALL Welthink brand, not our label) and EVERY one burned out within 3 months.
Now when we try and have Welthink sort out the warranty issue they completely ignore our requests. No emails returned, no phone calls answered and no replies to our Alibaba requests.
You get what you pay for when you deal with Welthink and Sonny in Virgina Beach, VA! Remember, if it sounds too good to be true it probably is and this is definately the case with Welthink Ballasts.

Save your cash and buy from a reputable manufacturer. Welthink manufactures crap ballasts. My company is out over $50K as a result and Welthink is running for the hills. Let my bad experience save you from learning the hard way!!!

I also can testify that these ballasts are complete SHIT. I bought 20 of them and all 20 were eventually faulty! One damn near burned my effen show down. And these pricks DO NOT honor their warranty. I have $4k worth of worthless burned out SHIT Welthink ballasts. Save your hard earned cash and buy from an established company with a proven track record. Welthink is a joke!!!
