Cheap RX/TX via Fake X-bee? (X-bee footprint devices)

Hello, hello.

I am looking for a new, cheaper RX/TX system to carry. I would love it if I could find a cheap, solid device that shares the footprint and pinout of an X-bee. There are a few out there that I have found, but I cannot find any review etc. to help me determine if they are crap or not.

Does anyone use such a device? What is it and do you like it?

 

...And if we forget about the X-bee footprint/pinout issue for a sec, are there any RX/TX systems that folks are using that they particularly like?

Bajdi and kariloy have had some luck with

nrf24L01+ radios. They are very inexpensive. I have 6 waiting on me to get some kind of uC up and running, so I can test them out myself.

I saw this on another bot that was recently posted.

I asked what he used and he said RN-XV wifi board.
