I got a refurbished Foretrex 101 off ebay for $65 shipped last may. They are no longer available having been replaced by the Fortrex 301; the best price I could find currently is here: http://www.tigergps.com/reforetrex101.html

For a 301, NEW, check ebay or amazon.com

My refurbished unit has held up fine to buoy racing and some distance racing (Surfside Beach, 3 days at Tradewinds, 3 days at Spring Fever, some big boat racing). I'm not saying its better than a new unit, nor that it won't die on Tybee. But it has the same warranty, is $50 cheaper than a new unit (the 301 has no new features other than USB instead of serial PC interface), and you can practically buy 2 for the price of 1, so WHEN one dies you have a backup. Just my 2 cents.

On that idea, how about using one of those food-saver type things? You know, you put stuff in the plastic bag, the machine sucks out the air, then heat seals the bag. You could seal it up, then put it in the dry bag. Would be great until the batteries needed to be replaced, I guess.
