Low latency Wireless RF transceiver modules?

Hi,

I'm trying to setup a remote wireless link between two PIC microcontrollers that are running PICBASIC. On the remote side I need to sample 2 analog inputs, and control 4 digital outputs, and I need the control turnaround time to be under 20mS. Since I'm new to RF I'm looking for a plug and play solution, that's why I've been looking into wireless cable replacement solutions.

So far I have found DataBridge modules from Starman Electric (www.starmanelectric.com), and AirCable modules (aircable.net). Is anyone familiar with these modules?

Thanks,
