We are looking for a wireless access point that works/designed for constant sub-zero temperatures (-10 F).  The generic ones we use that are "rated" for that temperature all die in about 6-8 months.  They are used in a very large freezer at a food warehouse so that handhelds can communicate with the server.

We had very good luck with the Aruba AP175 access points. We used them for an external point-to-point network to connect two buildings through New England winters without issue. They have a very ruggedized housing with seals to protect the AP, cabling, and connectors.

The Cisco Aironets are also good in this situation but more importantly are you using the APs in enclosures?  You need a good seal, moisture contamination is more likely to kill your devices than the effect of the continuous low temperature on the components themselves.

you can also put a small heater in the box, like a resistor, connected over the PS pins, so the temp won't drop very low, and dries a bit also

Cisco 1500 series APs are designed to be used in environments with temperatures as low as -40.  They are built with the correct enclosures so you just need to mount it.
