Emerald Cove timehares/memberships

I'd like to buy a used "B" membership/timeshare that will get me into Emerald Cove. My brother-in-law has a membership at that's how he defined his. He told me to look at CRA memberships, but I had no luck. Did I go to the right place? Is there somewhere else I should look? He said he paid like $1500 for his used one, granted it was years ago, and he pays about $500 a year in dues. I'm not looking to go through the typical sales route with Emerald and pay $5000. Can you help me? Send me a link?

Cheers!
