I spoke w/ Nico, the tech at ACR and he is an XC PG pilot from South Africa and knew what I was talking about. Rather than buying one of their discontinued units for $200 then possibly needing to spend another $150 for a new battery and inspection due the the old shelf life, I just bought a brand new model at the best discount I could find on the web.
This is the model he suggested: http://www.acrelectronics.com/product2.aspx?sku=2883
Here's where I just ordered mine: http://www.anchorexpress.com/ProductDet ... tCode=2883
For an extra $60/year I can use the beacon to transmit my location to my retrieve driver, etc: http://406link.com/406Plus.html

Just press THE button--before you come to a stop. You can deactivate it if you don't require rescue after you come to a rest. If you subscribe to the tracking feature, you use a different button. It looks pretty straightforward to me. I will not be buying a SPOT Locator now that I have this on its way and know that it can be used for retrieve driver alert with a $60 annual subscription.
