If you're handy with a soldering iron, kit K145 from Ozitronics will do
what you're after:

Look under "Data Acquisition & Control". It can handle up to four
temperature sensors. I built one a few months ago; it took me about ten
minutes. $34.50 including one sensor, $12.00 for each additional
sensor.
Hardware design by James Cameron, details and software here:

None of the software I found did exactly what I wanted, so I've written
a daemon which logs the output to an RRD database and/or to text files.
I've been running it at home for a month or two now and all that's
really missing is documentation. It'll appear on my web site (and be
announced on the mailing list) when I've finished, but if you want it
sooner, let me know and I'll give you the source (or an rpm if you
prefer).
Cheers,
John
