http://www.midondesign.com/index.html has a box w/ temp & humidity
sensing to serial port for ~ $135. They also sell the parts so you
can make your own for less.
Nagios touts http://www.nagios.org/products/environmental/esensors/em01.php
which is ethernet/web based for temp, humidity, light. It's around
$330.
http://www.spiderplant.com/hlt/index.html used to sell something for
around $100. They now have schematics and code. They focus on Linux.
I worked with one of the owners. Alas, they no longer sell stuff but
you can use their plans.
You might be able to use X10 based stuff. I imagine once you get all
the parts it'll be more expensive.
You'll see Dallas and 1-wire interface alot in your search.
Unfortunately, if you want inexpensive, you'll have to roll your own.
