I debated posting to this thread, as I have yet to make my first DVC trip. However, I will throw my two cents in and you can decide if it is worth the asking price.
We purchased SSR resale last October sight unseen. Why? Because we knew we were going to Disney on a reoccuring basis, we needed more room than a value room could provide, and we liked the idea of staying at any of the DVC resorts - even SSR. Resale was the only economical choice for us - perks or no perks. We were able to switch to AKV Kidani Savannah room at 7 months for our first trip. I have my second trip scheduled and have 3 different resorts I am willing to change to at 7 months for that, but if we have to keep our ressie at SSR I am still going to Disney. I am not picky - as long as I am in the Disney bubble.
So, I am more than comfortable with our purchase without seeing SSR. I DID buy where I wanted to stay: Disney property.
PS Dean - we did exactly as you posted above and bought in at the 150 point level. It seems to be the right amount... for now.
