In my opinion, they are not worth the price you will be paying. They have worse control of chromatic aberration, are less bright, and do not have a particularly neutral color cast.
They are great optics, but at the price you can get a new, second-tier that will have a warranty (Leica does not have a transferable warranty, at least on some models) and better optics.
If you are buying it for the prestige or mystique (collector's value), then go for it, they certainly won't "disappoint" in terms of view... But I strongly urge you to consider other options (the Meopro HD and Leupold BX-4 HD are both better options, IMO, for less than $500 USD, with a lifetime warranty).
