I agree with the comments posted by Chuck. Just one point to add to my other post....
If you want a really good, cheap moving map GPS system, then you may want to consider hooking up a cheap 12 channel GPS (such as my trusty eTrek) with some pocketPC device such as the Casio Cassiopeia. There are several packages on the market which run on these PocketPC devices, but the favorite I use is a program called Ozi Explorer. I can't remember how much it costs, but its cheap. There are two flavours, one which runs on the desktop, allowing flight planning and easy creation of routes and the like, and the one that runs on the PocketPC device. Maps and charts can either be scanned in and 'calibrated' or downloaded from places like Aeroplanner, already calibrated for use. I just downloaded a US World Aeronautical Chart for the UK, ok its the US flavour of chart, but it gives a great full colour zoomable moving map system.
I also use another package called Anywhere Map, which is a vector chart system. This is a EFIS type of system, which is excellent, though you do need to subscribe to the database updates which adds to the cost slightly.
All in all the cost of a complete system like this is in the region of £600 to £700 including stuff like Casio and the yoke mount for the Casio....
