Hi,
Some people confuse GPS with GPS + mapping software. If all you wish to do is find your elevation and lat/long then there are many cheap options.
For example, 2 years ago i purchased a 32 channel bluetooth GPS for my phone for just over 100 AUD. These days the same unit can be had new,buy it now price, for about 50 bucks on eBay.
The previous generation 12 channel GPS's go for far less, maybe 20 bucks.
Also if you look around there are small handheld 'hiking' gps's which are very cheap. People use these as electronic magnetic compasses, they are not intended as guidance systems.
When i go to a new site i turn on my bluetooth GPS and in under a minute it has a fix which I can read on my phone.
Cheers
Paul
