DVC members can also go to the DVC site and, after logging in, learn the point value of other WDW hotels, depending on the hotel and the season. They can also get a point-per-night breakdown of hotels in the Concierge Collection. The other traditional time-shares tend to be 140-180 points for a full week's stay.
As far as using DVC points to stay at WDW resort that isn't a DVC resort, the point values make it unattractive to say the least. Depending on the season, 150 points (for many people the minimum you can buy to be a DVC member) will get you a week in a MODERATE resort. Deluxes go up significantly from there. If you're renting DVC points, or renting points from someone else who can trade them in for DVC points, best to use them in a DVC resort.
