For those of us in Canada who are unable to find the AcuRite digital thermometer with wired probe (looked in 3 different WalMarts..), I found a similar thermometer at Home Hardware. Comes with a probe (6' of wire), and reads indoor/outdoor temps as well as indoor humidity. Can also be programmed to give off alarms at low or high indoor temps, outdoor temps and humidity levels, which I think is nice. List price on mine was $14.99.
Below is a link to it on the Home Hardware website:

Hope this helps.
