DVC is a cash cow. Dont worry there will be other places to stay in 2043.
For us, we waited for SSR to buy from Disney. Because we felt like there was something obviously tangible more for our money.
SSR from Disney will be an instant gratification kind of thing. You call, you buy, you book, you stay.
With resale there is the thrill of the hunt, but you could go through the process one or more times before you actually get your hands on a contract. We had a very fustrating failed attempt to buy into HH.
examine your travel habits. Do you travel during peak seasons? Then you should buy into the resort you want to stay at the most. For us, the only place we'd buy resale is Hilton Head, because we're far more likely to go there over the summer, during its peak season,than we are to go at the holidays to WDW. Everyoen says buy where you want to stay, but IMHO i think its only important at peak seasons.
Go over to wdwig.com and check out the resort photo gallery. You may look at the SSR photos and think, "yuck. wont stay there often."
Unless you find yourself longing for a sold out resort, buy from Disney. You know how it is. They just do it all better.
