hi bd,
when selecting a digicam you need to look for the resolution of ccd. usually given in pixels, multiply them and find out the real figure your self. the more MPs meana larger file size, finer details, better colour reproduction.
for home use a 3 MP one will suffice upto the 5x7 inches size prints.
second featture you have to look for is optical zoom.
the more better
do not fall for digital zoom as it is a software function and mods the image to give you an impression of zoom.
then you go for the batteries. the more simpler they are better.
i mean to say if you can find a camera with AA rechargeable batteries using camera it is best, proprietory batteries will cost you a bomb if you need to replace and you always have to keep spare batteries with you on a long trip. in that case AA is a better option.
also the storage card type carries a bit of price tag go for cf card > mmc card > sd card > memory stick in descending order as if you need to buy a new one it will be cheaper in that order.
avoid sony ones and they carry a big price tag if you need to replace or purchase new things.
then look for size and handy ness canon / nikon / olympus are the best in this regard.
also look for ease of operation, as if it is to be used as family cam you often need to get yourself shot by someone at some tourist location so it is must.
canon and olympus are the best to use.
www.imaging-resource.com

look at

imo you should get nikon coolpix 3700 / canon powershot a510 / canon powershot a85 within your budget
