Google is your friend! I simply typed "Omega Dynamic Chronograph" and he was willing to help me shop, giving me pages and pages of potential things to check out.
I saw several, some look in good condition, some excellent, others had seen much better days - wanted to see if someone in here had one in the back of their collection or dresser drawer that they wanted to sell. I've looked on ebay also, I've been out bid on several and some have gone too high for me to continue to bid.
