They're hard to find, at least inexpensively. I've found several systems for >$700 that have some nice features, including cameras (http://www.rackbotz.com/) and multiple wireless measurement systems (http://www.microstrain.com/WWSN.html) but they've all been slightly out of range in the cost department, or have been aimed at a different market than what I was looking for. Using the Cisco temperature MIB has been pretty much the standard to this point.
After some extensive hunting a while ago, I found this: These guys make a nice (fairly) inexpensive module that I think wins the competition. It has a large number of measurement and switch inputs, runs a number of relays (built in) and seems to be fairly customizable. The bad news: it's not "native" SNMP and requires some sort of little C or Perl module to do screen-scraping. The vendor provides a sample MRTG script, so it can't be that hard.
http://rms.nethop.net/ $395 plus a lot of features, including running on minimal voltage.I haven't purchased one of these yet, but they're close to what I've needed several times in the past, and I'm looking for excuses to purchase a few. Any of you who pick one up, I'd appreciate it if you could send feedback to me personally. It seems to me that there still is not any widely-advertised, inexpensive temperature gauge that is network-accessible (SNMP) which is surprising considering the amount of damage that can be done via overheating in a datacenter.
[Note: before I sent this, I read Robert Boyle's followup message, which has some interestingly low-priced alternatives. Perhaps I have been looking in the wrong places. In any case, the RMS device has some additional features that may make it worth examining for the remote or low-voltage wireless sites that are starting to appear with some frequency here in in the Pacific Northwest American area.]

I've searched the archives, and didn't see anything current. I am looking for a small, cheap, simply device, that can measure temp and be polled via SNMP. POE would be a plus.
