For my use (macro only, and one lens only), I am thinking that I should just get one of those cheap EOS e-bay adapters and see how it goes on my 3, and then perch and wait for an FD adapter to come up. FD cameras are great for macro pix. Mirror lockup is simple and there are never any problems with anything in use. (Servicing issues are another story.) Also, one less old camera to lie around and need service.
