I am trying to start a manual SLR outfit with a decidedly limited budget. I have decided on either the Nikon FM or FM2. I'm hoping that someone who is knowledgeable on the subject can specify the exact differences between the two. The bottom line is this: The FM seems to sell, on average for about 40% of the cost of an FM2. I'm just trying to figure out if the FM2 is really worth paying more than double or if I'll regret buying an FM instead of an FM2 later on. Thanks in advance for any help.
