I've recently rejoined the back to analog revolution. i picked up a nikon fm10 pretty cheap so that i could start shooting film again. i'm looking for good prime lenses that aren't too expensive. although i'd prefer to stay with nikon lenses my limited budget suggests that i might look for some hidden inexpensive gems. any suggestions? or am i dreaming 

Eventually you will find yourself using your camera in situations where a faster lens is necessary. For example, indoors. Or winter. Or when you need a faster shutter speed. Not to mention that very slow lenses are harder to focus on an SLR. It seems penny wise and pound foolish to limit yourself to only slow lenses.
