I know it is a lot of money but it has a battery that last 5 years and if you really did crash out of sight out of mind, you have a much better chance of being found in your white plane in a snow storm, than any current 121.5/243MHZ ELT.
They cost less than $900.00 (
Chief price on ME406 ) Vans has it also (

It does not transmit lat/long but 406mhz is way better. This model also only needs one antenna, which is nice.
The advanced units have GPS interface and dual antennas. They are double or more the money.
From Van's catalog: A 406Mhz ELT is not yet required, but the 121.5/243Mhz band will not be monitored after Feb 2009. I am guessing it will be required sooner than later?

PS after some research I guess the FAA as of now (politics) does not have the coconuts to mandate the change over. However that does not change the "sarsat" (search and rescue satellite) will stop monitoring for 121.5/243mhz end of 2008 early 2009. NO satellite search and rescue locating.

So if you want to go cheap, than its OK, I guess, but consider the new stuff. I have a Artex 100-4 and it is a real piece of equip. I have had ACK (yellow) and friends have had the Ameri-king (orange). They are OK but they are a bit cheap and light duty compared to the Artex.
