The best buy with a camera as old as this will be one that has been little used, i.e. lying around for a while under favorable storage conditions. A camera like this may well have shutter speeds that are too slow and will almost certainly benefit from a service. The service should also cover the film wind, dried-out lubricant can cause this to skip frames. After this, it is certainly capable of delivering many years of reliable service with moderate use (say, 40 or 50 rolls a year). The only problem may be that the viewfinder mirror can become dull if exposed to atmospheric pollution over long periods (making for a dimmer than usual focusing image), but this problem is no worse than with any other camera.
