The "What camera do you regret selling the most" thread was interesting although I never sold anything (yet) so I don' have any regrets. It had me wondering... If you were forced to sell everything and keep just one camera from your collection, what would it be? Lets assume that this will be the one and only camera/lens that you will have for quite a number of years. For me, it would be a toss up between my Pentax 645 w/ 75mm lens or my Leica M3 w/ 50mm. Probably my M3 since it should still be in good working condition even after I'm well into my senior years.
