Generic 433 MHz device (to replace a Telldus Tellstick Duo)

Anyone knows about a good and reliable 433 MHz transciever that one can use to receive 433 MHz data from temperature sensors compatible with Telldus Tellstick Duo?

I use the RFXtrx433XL from RFXCOM for all my 433Mhz stuff

Maybe this is what you are looking for:

I use this my self (it also can transmit to 433.92 MHz devices to operate switches etc).
