I have a nikon coolpix 5400 and have been VERY happy with the results. In fact the macro lense manages to pick out details I can\'t even see sometimes even knowing they\'re there after seeing the photos, which has forced me I think to improve my painting, haha, to get rid of those unwanted details. for miniature photography I really haven\'t wanted anything more.
But this camera is very nice both in terms of miniature photography and everyday photography, it is compact, but not too compact, you can add addaptor lenses to it, so you can add telephoto, wide angle, or even a real macro lense if you want (although not really needed).
The bottom line is that I have been thinking about getting a much more expensive Digital SLR, but when I do, I fully intend to keep this Nikon for my miniature photography, since I\'m 100% happy with the results.
This model should be easily in your price range as well
