Check out FareBrowser. It doesn't give you a map but it does let you set any RT threshold price you want. It also gives you many other options for filtering the flight search, e.g. by carrier (or alliance); advance purchase time; min/max return time; etc.</font>
FareBrowser looks nice, not of too much use to me since my city is only a destination, not an origin (LAS)
