Newbie Alert!!

Hi you all,

I would really appreciate some advice. My 14yr old daughter is showing a real flare for photography, she is planning on taking A level art and is thinking of including A level Photography, hence I need to buy her a decent camera, JOY! ;-)

Iv'e looked at some DSLR's but I don't really know what to look for, and they are so expensive!! I really don't want to spend too much money as I don't even know if she will keep it up, you know what kids are like?

So please could you advise me on some good, starter, probably 2ndhand options, under 150 if poss.
