Yahoo travel is porting travelocity, and it looks like the data presented in that fare roundup is similar to that on the travelocity dream maps (also available through yahoo). Since the dream maps are always round trip searches, and the fares shown *usually* are the same in both directions, you could use dream maps.

If your destination city is covered by the "best fares" feature of www.air-fare.com, you could also look there.
