Pete:
Shaunie has made some really good suggestions. If you do get interested in an original StreetPilot (black and white) or a StreetPilot ColourMap (not a "III"), post a note here and I'll give you a detailed briefing on the pros and cons of the unit you are looking at.
There are a couple of major "forks in the road" that you need to make decisions on, concerning what capability you want from your GPSR.
In simplest form, it breaks down like this:
1) Do you want detailed, street by street display of where you are?
2) If so, how much detailed street by street information do you want to be able to store in the GPSR at any one time? Just enough for your city and a 20 mile radius? Or enough to support a 3 week tour to Vienna and back?
3) Do you want the GPSR just to tell you where you are (basic location function), or do you want it to tell you how to get to a destination (autorouting function)?
Answer the three questions in order, the first "NO" answer is also an automatic no to subsequent questions. The cost of a GPSR to do what you what works out like this: 4 NO's, about USD 150 to 250, 2 NO's (yes to 1 and 2a) about USD 300 to 500, 1 NO about USD 700 to 1,000, and YES to everything, between USD 1,000 and 2,000. These rough price guesses are net of tax, for European units.
This is overly simplistic but should help you narrow things down.
