The sensors on the Azel dual digital temperature gauge can supposedly be extended by several hundred feet: (broken link removed to http://www.azeltec.com/catalog.0.html.0.html#DIGIT-STAT)
The units come with two sensors and a dual display for around $75. Not as slick as jebatty's or nofossil's systems and not as cheap as Eliot's, but it is an easy option. You can also purchase extra sensors through Azel. If you had a way to switch sensor inputs, you could monitor many locations for a reasonable cost.
