For truly ace digital camera info check out this site:
http://www.dpreview.com ( and in particular the
'Reviews' section - see menu item on the left hand side ) It is BRILLIANT !!!
Indeed on the strength of it I purchased a
Canon PowerShot G2 - and I could not be happier with it, e.g. it's better than my Canon EOS SLR (which is saying something).
P.s. Also have a look at the 'Reviews' section (link at top of page) available on
http://reviews.zdnet.co.uk which includes some handy links to various favourably-priced on-line suppliers ( i.e. click on their 'check-prices' link(s) ).
