I'm going through the same thought process. The difference is cost is the difference between their age and desireability... and some will talk of the technical differences like shutter capabilities and coatings. If the chrome lens is is in good operating condition, or can be brought into good condition by a routine overhaul... then it is a good option. Only concern (and not much of a concern really) is that they take B-50 filter/hood and all of my other lenses are B-60. But there is no compeelling reason that I know of to not buy and use one. I've seen people write that they will not buy/use a chrome lens because ofhte EV interlock... but that's nuts in my opinion.
