Ever heard of this outfit?

Never heard of them. Looks really cool, though. I'm impressed by the range of sensor options that they have.

As far as I can figure, the cheapest 8-channel temperature logging system would be $440 for the logger, sensors, and software. Not clear if you also have to buy some network / interface to connect it to your PC.

Looks like a powerful and easy to deploy system, especially for anyone who needs to measure a lot of different things. For the hardcore DIY types, there are somewhat less expensive approaches such as 1 wire.
 
Dataq Instruments (www.dataq.com) sells some low cost starter kits that you may be able to use. I use their higher end equipment for general data logging in our plant and it does the job and holds up fairly well. The DI-48U is an 8 channel single ended (common ground) unit with 10 bit resolution for $50. You will need to use a PC with an available USB port. Find some low cost temperature sensors like the National Semiconductor LM34 series for inputs and a power supply.
 
Also NF, since I don't get on here much anymore, was wondering...you were trying to develop some type of control system, with ODR??...how did that project turn out?

OK, I give up. Who (or what) is ODR?

I used the four channel analog and it worked great. The free software was excellent - has loads of otions and configurations. This product has the best bang for your buck - IMO

I was looking for some temp sensors like those. Do you know of any other bands?
