I've had an m4p and m6 in my time ... Sold them both, don't regret selling the m6 as such as I prefer the functionality of the r2a voigtlander, but I do miss it! It just felt right!
Whenever anyone says they can't understand why Leica has the cachet it does - I ask if they have held one and raised it to the eye. I don't think I'd want a digital one but I'll let you know when I win the lottery.
