We use these guys as our vendor for ballasts here at the office (just placed an order for a case of fluorescent ballasts yesterday as a matter of fact).
They are a good vendor. No troubles, and they'll talk to you on the phone if you have problems. They are owned by a parent company called Service Lighting and Electrical.

in type , you still have to power the bulbs , so the differents should not matter, so you should be fine
Sorry to disagree, but it absolutely does matter. MH ballasts and lamps come in two flavors, probe start and pulse start (pulse start is also referred to as HQI in the aquarium industry).
A double ended lamp requires a pulse start ballast to ignite them.
Single ended lamps are usually probe start, though there are exceptions (Ushio SE lamps are pulse start, for instance). If you want to fire double ended lamps, then on their site, after going to the ballast section, select "pulse start HID ballasts". A pulse start ballast will also ignite a probe start lamp, so if you have plans to use DE lamps or plan to use them in the future, then invest in a pulse start ballast.
