Sparkfun.com sells alot of the Laipac products, along with the mating connectors(important). THe RF-24 G is a shiftin protocol MSB first. There are some examples on the Sparkfun for using a PIC. The units work, but at 2.4 gig, they do not penetrate walls well. I guess there is a 900 MHz version that will get far superior range. Hope this helps...
