Hi CJ
I use Memory Map with a Garmin Etrex Summit.
The latest version of MM is a vast improvement on the previous one. I've got the whole of the UK mapped and I think its worth paying for it, but it depends on where you ride and how much you would use it. I use mine for riding and my work with the Air Cadets - DoE walks etc, so I use the whole of the UK.
The latest MM version has all the right to roam areas on the maps. It also lets you change the route colours, very handy if you have several routes criss-crossing each other, you can even thicken the line, and then turn it transparent so you can still see the map markings underneath, little things but make a big difference.
A nice feature on the National Park maps is the aerial photos, especially if used with 3D mapping, you get a really good idea of where you will be riding.
I think you've made the right decision with MM!
