OMS batteries

Hi

Does anybody knows where to buy an OMS battery? Mine is busted. I tried to find it in at least three diving stores, no luck. Actually I have one in back order with a large Georgia retailer, the price is huge too.
Does anybody know a supplier or a diving store with a reasonable price for OMS H.I.D. batteries or a generic replacement?

Take care and safe diving.

I bought a battery for a Hawes light at Batteries Plus. They looked at the battery and assembled what I needed. $70.00.
