There are damned few alternatives. The Garmin is the only one I've ever heard of in the under $100 price class. At $300-$400 there are a few alternatives. At $1000 and up there are even more alternatives. If there were a market for several hundred Plug-N-Play systems, I'm sure someone would be delighted to serve that market for $100-$125 each. $70 for the Garmin $5 for a DB-25 or DB-9 connector $1 for 5 feet of cable $5-10 for a 5 Volt "wall wart" $1 for a mating connector for the "wall wart" A soldering iron, some solder, and you're in business. Pricing is "S.W.A.G." D.I.Y. is a bit cheaper. _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
