There is some nice software called Artisan and a list of temp.
dataloggers that has been developed by home Roasters on Home-Barista.
Check out these 2 linkshttp://code.google.com/p/artisan/and This is
the thread (now on page 10) of the development of it to read through.

Omega has an inexpensive USB thermocouple datalogger now for like 
$80. Works well...

There's lots of them, but sometimes getting the interface spec is hard.

well, after looking around, i found the Extech 421509 which has a 
bi-directional RS-232 port.  it seems like just what i was looking for 
allowing me to interface the thermometer with my pc.  but, convenience 
apparently comes with a price (tag)... $289.
so, i decided to go pseudo-old school.  i'm going to use the digital 
thermometer Tom sells along with a small little program i've written that 
displays target, ideal roast profile graphs while overlaying time,temp 
points entered realtime (obtained visually from the thermo).  my thought is 
that if i can see the roast profile progressing graphically, i can better 
anticipate and make adjustments to the heat.  and, by using a digital 
thermometer and having the pc graph it for me, i won't have to fuss over 
counting grid lines on paper.

I've got a couple of devices that do this.
One is a cheapie DMM with an optical RS232 port ~65$$, TekPower
Dt9602R. Came with K-type probe and usual DMM probes for volts, amps,
etc.
One was uber cheapie dual thermo USB device from fleabay, shipped
straight from China, $25. It has both an environmental temp and a
K-type connector.
I've been playing with the Typica program by Neal Wilson, but it
requires one of two expensive-ish devices by National Instruments and
so I haven't made that leap to really using that tool.
I am interested in the other tool that is using the opensource device,
but haven't made that leap either.
For one, I'm back to just using the B16k with this dang aggravated
tennis elbow keeping me from all my fun hobbies. I don't feel like
grabbing a 600 F drum out of the BBQ and dropping it because my arm
won't work right...
