I upgraded from a Visor Deluxe - to a Zire 72. Big difference, but now the Zire 72 is no longer being made. Check out what you want to do with your handheld and act accordingly - if you have a lot of data to import into it, then get a top of the line PDA that will not crash your wallet. All you can do is see what is out there and go for the biggest bang for your hard earned bucks.
