Unfazed and others... The concept of a home made GPS/VOR/NDB approach is alien to some people, although I now accept it could have its uses. The problem a lot of us older pilots have, is the one about being in cloud without a radar service...... You rely on the Big Sky theory, in other words that no-one else will be in your cloud. This will work 999,999 times out of 1,000,000. Then you have to think like the national lottery, it COULD be YOU!!
I have flown in many nasty places, often without radar cover in very poor weather. We had an emergency letdown GPS procedure that was just that... An EMERGENCY plate.
Risk assessment is part of life these days, the chances of a mid-air collision are not great, but they are there. So "Do you feel lucky??"
