Well I flew one yesterday at PIK. We tracked MAC VOR, then came inbound from MAC, tracking the PIK NDB. I ended up 100 mts left of the beacon, and straight down the PIK runway. We then broke for a VFR let down. Very satisfying, and I was pleased at my tracking inbound. Once you understand your plus and minus, and get your SA sorted out, I think it is great instrument.
May well, when all else fails, get you out of a situation.
Oh, and had the 430 turned off!!!!
