Why not combine the best of both worlds and get a FlyAngel?
I've recently been introduced to it, FANTASTIC bit of kit - it simply shows your position overlayed onto a digital CAA half mil chart, and no more, minus the basic ETA and fly DCT functions etc.
Just to clarify, it is a GPS, personally now my favourite. It really helps you to gauge what speed you travel over your charts, and it means you can see your position and pick out features along your route with great certainty. It also helps your map reading skills, and as an aside, because all the newer CAA charts have frequencies next to most ATZ/MATZs etc, you can just zoom in and see info like that as well.
Worth looking into!
