Mariner9, the nav aid I quoted above is only £13.99. It might be a lot for a small piece of plastic, but when you're spending £150 /hr flying, what's another £14?
Especially since it's so helpful! Anyway, I'm not disagreeing with what you're saying, it definitely makes sense to shop around with this kind of stuff. For some reason if it's aviation or wedding related the price goes up ten-fold.
I agree on Sky Daemon. I have their GPS and planning software, and it's excellent. However, my primary method of navigation is still with a chart. If the GPS breaks and you can't remember how to use the basics then you're (maybe) in a bit of trouble.
