Tango, do you use yahoo/travelocity/expedia fare trackers to check fares daily or are there better tools. I am also aware of smarter living and a few other sites but am not aware of too many sites (other than the big ones above) that will email you when fares of interest to you come down. I am beta testing orbitz but have not seen this feature there yet, but they will probably have that on launch or soon after.

I am still looking into professional tools of course (though I am not in that "profession").
