250w Dual Ballast

[reefs4life]

Hello everyone, I'm looking to change the ballasts on my 48" MH fixture but I wanted an opinion on which ballast would be good. I looked at a Blue Wave 2 Dual PS Remote Ballast, a Blue Wave 7 Dual HQI Ballast and a Coralvue Dual Ballast. I'm going to try to run two 15k XM bulbs. Anyone have any suggestions on which ballast I should use? Let me know, thanks

I forgot to add...if anyone has of these ballast would you mind putting up a pic please and showing me what the attachment for the MHs looks like on the ballast, I'm talking about the kind of connection it has for the lamp cord. Thanks

Can anyone help me with this? And I'm also adding a PFO dual ballast to the list. Thanks
