The 5100 was semi ruled out as it is an older camera and seems to have a few idiosyncrasies going by the reviews.
The 3200 looks good but I am worried that I might feel it is limited far too quickly. The 5100 has the same sensor as the 7000 which was very good. But the 5200 has the af of the 7000 which also was good.
I am wondering if I should bite the bullet and go straight to the 5200. It is available in my local camera shop so I could pick it up tomorrow (but then they have all 3 so in itself that isn't a selling point - but it isn't a limiting point either unlike for any of you in the states where I believe the 5200 isn't yet released.
I have a growing feeling that if I don't go for the 5200 that I'll be back in the store in 6 months to buy it anyway. Following Len's comparison I can't help but think it would be the right choice. And the other post I've just seen from Len about the lenses on the 3200 seem to support that I could use the 5200 with my existing lenses (18-200 VRII, 55-300 VR and 35mm 1.8).
Darn but this is hard - why can't Nikon make some really bad cameras to make the decision more obvious
