Reading what you guys have written, It's all coming back to me now why I never fitted one in the Aircraft! I remember getting a rush out of Having to establish position when in doubt because of airspace restrictions etc. Doing things theb hard way was actually part of the fun. When GPS came out, you'd meet the village idiot flying around Europe,when previously he wouldn't make it past the tea bar door. But like I said earlier, The boot's on the other foot and I am now the 'village idiot' perhaps the difference is I will use manual navigation even though I'll have a GPS in every locker and enough Duracell batteries to power a Fridge Freezer!
I saw a mention of self scanned Raster charts.
I found this programme which does that and provides lat long positioning from sextant sightings too. I have yet to learn how to use one though but it looks fun and a useful backup to my sackful of GPS devices/battery packs
