I have a 48" 4x55w lighting fixture (straight pin) with two switches to operate each set of two lights. One of the ballasts recently died on me and I am wondering where I can get a ballast for 2x55w that isn't pricey? I would consider switching to T5HO but then I'd have a partially working PC fixture that would go to waste and I probably wouldn't want to do that. Any help would be appreciated, thanks in advance.

You can order a suitable ballast from AH Supply. They use that size bulb, and their kits contain a ballast that operates two bulbs. Or you can order the ballast from Fulham directly.

Ahsupply uses workhorse ballasts. To be exact workhorse 5 ballst.
Heres a link where you can get a replacement
