flourescent light sockets

I just made the pilgrimage to Home Depot, this time to get sockets for
flourescent lights. I am looking for a right angle mount socket that i can
fasten with wood screws to the inside of the hood. The only right angle
ones they had appear to be sockets for metal lamp fixtures (price a little
over a dollar). The aquarium store wants $14.00 a pair for the endcap
sockets. What is a good source for FL sockets and what do they cost.
