Thanks for the help everyone! Got the sensor working very well...went with the A1302 hall sensor and can use it to sense my magnet a good half foot away!

Good for you! Do you have a project in mind that will require a Hall effect sensor?

Personally I'm a fan of old fashioned reed switches, cheap and simple.......

If a reed switch gets permanently magnetised it jams closed - hall effect sensors have no moving parts, are smaller and less breakable.  Reed switches also affect the field they sense whereas hall devices don't.
