Hello Adrian,
Thankyou for your reply. I had initially looked at the sony DSC-P200 but was put off by comments concerning the relatively poor picture quality compared with the DSC-P150 and the relatively more expensive Sony memory stick.
Looking at some more reviews, the Nikon Coolpix 7900 has increased in my estimations and I have noticed that it has won the 2005 TIPA award for best Digital Compact which I suppose says something. I won't be doing lots of night work but I want to be able to adequately take pictures in low light or nightime if the situation occurs.
Bit concerned about Ixus line potentially turning people orange! I have seen some day shots from the Ixus and it does seem to produce generally good results. It certainly is sleek!
Still undecided

, but thankyou for views, much appreciated.
