Hey i purchased one of these new about 12 months ago.
It was through a chain of stores here in SA called 'SPRINT AUTO PARTS'.
Not sure if they have this chain in eastern states, but they were able to get me one in under a day. It was around $100.
It may have been for a TA23/8 or something similar but they were able to help me out and find the correct item for my model.
Didnt think it would have been so hard to find one... mine wasnt genuine either.
