Below is a link to the e-bay seller, I told him that I would post here and he agreed to offer a discount to anyone that I sent his way. Put the word Beer in the subject line if you contact him and he should give some discount, not sure how much. He is listing them for $15 each, that breaks down to $7.50 per SSR as these are dual. That's about what the Chinese ones cost direct from China.
