hi

apparently (boyfriend works in an outdoor shop) the gecko 201 is WAAS compatible and will give better accuracy than the etrex (its about +/- 3metres as opposed to +/- 15metres).

The iFinder Go is also good for a budget one, about £90, with WAAS.
Might be worth waiting for the GPS phones, coming next year. Or if you have a PDA, then a bluetooth GPS thiingbob could be used with it - works well with memoymap (does that cover your foreign land??)

hope that makes more sense to you than it did me.
