Ha, I just went the opposite route, from Nikon to Minolta. It was kind of accidental, really. I found an X-700 outfit in Goodwill one day for $10 (camera with the 1.7/50, Albinar 28mm Macro, Sigma 70-210 Macro, and the 280PX flash), and figured I could turn it for a decent profit, or trade for Nikon gear. The camera had some problems, probably caused by some dolt who tried to crank the winder with no power on the camera (big problem with all electronic models). So I set about looking for another body, at the cheapest possible price so I could offload the outfit.
Hey, Minolta MF stuff was cheap! I found a 500mm mirror for much less than I would have to pay for a Nikon version. And there were lots of other things that caught my eye, particularly the macro ring flash that I got for a song. Well, $63 actually, but that was still much less than the Nikon one I used to have was going for. I wound up with six bodies (one an X-570) because to get a particular lens, it came mounted on a camera. So I have a decent kit of Minolta gear now, though I haven't abandoned the Nikon line. Even picked up three more Nikons while partaking in the Minolta GAS.
I had an FM that was my main camera until I got an N90s. A few years ago, I had to sell off most of my gear, and kept the N90 outfit because it was the newest stuff I had. And a Yashica GTN, because it was a rangefinder, and for other more sentimental reasons. But my situation improved a bit over the years to where I started to buy cameras again, always looking toward expanding my Nikon stable. But there are so many cool and great cameras out there, that it's not hard to get sidetracked once in a while.
But I found an FG decently priced, then a Nikkormat FT came in a box of stuff. I replaced that with an FTN. Then my all time favorite, the F2S came home with me one day. After that, an FM, then an FA.
The FA is one intriguing camera. It was Nikons' first foray into what would become their Matrix Metering System, and works quite well. Four different modes of operation (Program, Aperture Priority, Shutter Priority, and Manual), and a new dedicated motor drive, the MD-15 (though the MD-11 and -12 can be used on it). An MF-16 Databack, and SB-16B flash round out the options on it.
Mine came with the MF-12 databack, which is for the FM2 actually, and on my camera is totally useless because someone broke the cable that connects the back to the camera PC socket. It also had the MD-15 drive, and a 1.4/50 AiS Nikkor. I haven't shot it yet because the MF-12 doesn't fit the body correctly, and I'm afraid of light leaks. It is battery dependent, though there is one manual speed of 1/250 to use in case the battery dies. That is also the top sync speed when using a TTL flash. It also has an LCD panel similar to the one on the F3.
I would say if you would get an FA, you wouldn't find yourself lost as to what the camera is doing, since it has so many similarities with the X-series Minoltas. Well, other than the lens bayonets in the oposite direction, and the camera and lenses are heavier. Oh, and the Nikons are much more reliable than the Minoltas.
