Daylight-Visible PDAs?

I'm looking for PDA units which are usefully visible in daylight conditions outdoors. The daylight visibility is a major requirement, along with WiFi built-in. I know about the super-expensive rugged things like the Recon line; I'm looking for something that isn't THAT pricey. Any suggestions? (I'll be posting this a couple other places, so don't be surprised if you see it in more than one place)...
