If you're just an ordinary PPL with no ambition for higher things, the NPPL "medical" is a joy. I converted a couple of years ago, and though I can't do lunch in Le Touquet (been there, done that), my visit to the GP the other day lasted about 10 minutes and cost nothing. He checked my medical history on his computer, signed and stamped the form and I don't have to go back till my 65 birthday in a couple of years.
