Anyone Know Where to Find...

The FCC puts severe limits on the power that can be used by devices to transmit data. They are limited to 1/2 the power allowed for things like handheld RF remotes (e.g. HR12A Palmpad). 75-100' line-of-sight is probably near max for devices that are following FCC Part 15 rules. Many of these use

433.92MHz which is subject to the FCC limits (but for which CE allows much, much higher power in Europe).

You can probably improve this significantly with a better antenna and a preamp on the receiving end. See the thread on improving RF range from a few days back to get an idea of how much this helps.

I d>a remote temperature transmitter/receiver with decent range? All the ones
