Jeremy,

     I use a Palm lllxe (an older model) with John Manson's CN
software.
These older Palms can still be had on ebay for under $30 US. John
Manson's software can be purchased at pilotnavigator.com/beta.html for
$15 US. Installing Big Clock freeware will facilitate internal clock
time setting. Using 2 AAA lithium batteries extends battery life
significantly. My other nav computers are a Tamaya NC 77 and NC 88
which are now serving as back-up. e-mail John Manson questions at
john.manson@sympatico.ca
