Does it have to be second hand or new? Compact or SLR? Can you play with the budget a bit?
If its a compact you are looking for I know the Canon Powershot series have always been popular. My other half has the A95 and it is a nice little camera.
If you can bang another £20 on top of that £200 you can get a Canon Powershot A1100 IS Digital Camera.
21.1 megapixels
4000 x 3000 pixels image size.
4x optical & digital zoom.
Face & Motion detection.
Although I am fairly new to the photography field it looks like a nice little camera
