I bought 2 resales from The Timeshare Store, one at OKW 5 years ago and one at BWV 2 months ago. Both transactions were very smooth.
FWIW, I also tried Jaki at many people's suggestion and did not find her to be very helpful. She finally contacted me 3 months after my initial 2 phone calls to her. I wasn't looking for anything particularly exotic, just a BWV resale with 150-300 points with a June or later use year with banked points. She finally called me with a contract 2 weeks after I received my new membership card from the contract I bought from The Timeshare Store (200 points, 100 banked, August UY).
