What is the best to buy Nikon coolpix L12 or Olympus FE-230 digital camera...?

Have you compared them side by side? If so, which one has the most features you want in your camera? Try steves-digicams.com or dpreview.com for reviews.

IMO you should visit a real camera store - a store that only sells cameras, not 10,001 other things and cameras - and do a side by side comparison. The salesperson will give you intelligent advice and you'll be able to try them in the store. You should then BUY the camera from that store. You might even get an hour or so of instruction with it.

NEITHER! Get a cannon powershot SD750 or any Canon for that matter. They really are the best digital cameras out right now.

BUT if your heart is set on either one then get the Nikon Coolpix L12
Nikon is known to be the pioneer for introducing new technology and I dont think it got bad reviews.
