Just curious if anyone has actually used this transceiver with an AVR.. Was shocked to see Sparkfun's price is now up to $20/ea, but only $2 here:

You are comparing the price of a chip and a complete module. $3.50 is the cost of the chip from Sparkfun.
I have used it with AVR, works fine. Range is not so good when compared to the older chip nRF2401 (at least as used in the RF-24G module). This is when using the 250Kbps rate (which is not available in nRF24L01).

why not use one of the IEEE 802.15.4 modules instead of a single-vendor product?
