If you can find a member to rent from on a regular basis, I'd go with renting. I think the cost of a point is just too high these days. We paid about $50 a point for our initial points in 1997 and I just can't see paying more than double for them.
Dues continue to go up every year. That's one reason we sold off some of our contracts, we were paying Disney over $2200 a year just in dues. It's more reasonable now and we get one really nice trip a year for about 8 or 9 nights in a one bedroom. And we'll add a few nights at the beach before or after our WDW trip using cash. We prefer Gulf Coast beaches, so Vero Beach isn't our cup of tea. Some folks love it, but we prefer the Gulf.
If you want to do Disney every year, it may be worth it. But if you want to do something else and only do Disney occasionally, a small contract might suffice and use banking and borrowing every two or three years to get your Disney fix. Don't buy Disney to use it outside of DVC. It's just too expensive to use for non-DVC trips.
