I have a range of fd bodies including regular use of my ae-1 program and new f-1. the canon squeal is easily sorted as it is a mirror lubrication issue rather than a major fault. the av-1 is certainly less than the ideal as far as the manual focus canon cameras go but very neat little body. if you are keen on getting into the fd bodies i would go for the f-1 as it is easily the best of all. having said that, the a series are a great entry into the system and are very cheap and reliable. if you know you can get a working one cheap, then get it. you can always extend the kit (at minimal cost) if you take a liking to it.
