Garmin 12XL GPS
This unit is not marketed as an aviation GPS, however, if all you want is the ability to set GOTOs and have a reading of ground speed and ETA then having this unit clipped to your instrument panel or stuck to your knee could, at a price considerably lower than the official aviation units, fit the bill. Add in up to 500 of your own waypoints and you can make up your routes and divert to alternates with ease. Be aware that without the aviation database you are not warned of controlled airspace you may be approaching, make sure that you use this in conjuction with, and not instead of, a map.

Garmin 295 GPS
A 16 colour display and massive inbuilt aviation database means this unit is for the serious tourer. You can 'pull up' any one of the airfield information pages to see runway information, elevation, frequencies etc. You can scroll a cursor across the screen and with a click of a button get an instantaneous readout of bearing and distance to that point, very handy. You are able to de-clutter the map and show as much or as little of the detail as suits you, this with the zoom in and out feature makes this a very nice unit to have, even if it does cost over £1000.
