Thanks oenophilist for starting this thread.
I've been a member for a more than a year, fortunately at the original price, and am very pleased. I've taken 8 "entire plane only" flights and one HPN-VNY G-IV shuttle. Although I'm not happy with the new shared concept, the new affiliations have brought a lot more inventory into the mix.
I've renewed for another year (fortunately grandfathered at the old rate) and will likely get a 2nd membership for Mrs. SFO (I'll get a referral fee). This will enable us pretty much "buy out the plane" for light and midsize repo flights. The second membership will get us two shuttle seats at no extra cost.
