NDB approaches aren't the be all and end all of piloting skill that will magically turn you into some kind of Skygod if you can fly one, like some here are making out. It's just a skill, like any other, that isn't particularly difficult if done regularly but will perish if not.
I've flown plenty on LPC/OPCs, a few in anger and some just for the hell of it and the only thing I can meaningfully conclude from all this is that NDBs are useless.
Sometimes they work fine and you end up just where you want to be. Sometimes you fly the thing like a pro and pop out at minima a mile or so from where you were last time you flew the approach - even though the needles are reading the same. Sometimes you can be flying one nicely and the needle suddenly decides to take a 20 degree swing due to one of the myriad errors these archaic pieces of kit are prone to.
So... in conclusion, you'd be mad to use one where you have better options and it's about time they were phased out.
