Field data collection, GPS receiver, GIS and ArcPad

I am looking at replacing my Trimble hand held units for laptops simply becasue of the complaints Ive received from the cumbersome touch screen and data entry of the GeoXt units from Trimble.

The data that my field workers collect has got to be fairly accurate, so less than 3m which Trimble can do after you run post processing using GPS Analyst. Does anyone know of a good, accurate GPS receiver solution for a laptop that can be used for data collection in a program like ArcPad? Are there special receivers out there designed specifically for data collection with high accuracy? I know a few of them are WAAS enabled.

Thanks.

You could go with a Bluetooth Trimble device such as the ProXT http://www.trimble.com/pathfinderproxt.shtml

If you are always going to be post-processing, almost any receiver should work, shouldn't it? Or do you need more than the long/lat plus timestamp in the raw data for post?

Why not borrow a consumer-grade receiver, take a few readings and see if the post-processing still does the job?
