For all things Edge 800 - see the excellent work of Frank Kinlan
His excellent guide includes how to upload OSM maps as well as basic (and advanced) use
What you need to be aware of is the mapping. The cheapest Edge 800 option is without any maps, the next stage is the OS Discoverer, and the most expensive includes the cadence and heart rate monitor.
I went for the OS combination.
I have an Edge 800 (upgraded from the 705) and it is easy enough to use - one bonus is the ability to use the OS Maps on the computer with BaseCamp as well, avoiding the costs of Memory-Map, Anquet or similar.
If you cannot afford the Edge then the Bryton 50 (£160) is half the price of the basic Edge 800, includes the ability to take OSM maps, and you can get the unit with cadence and heart rate for £230
