Funny you should mention the Nikon Coolpix S8100. I've had one for review for a while now. Here's a link to my S8100 gallery:

A lot of those photos have a fair amount of post-processing. But the S8100 has excellent image quality and specs for a pocket superzoom. I just always try to squeeze the most out of my photos. Pocket superzooms are my favorite point-and-shoots right now, too. If you want some more options, check out my pocket superzoom camera guide - note that the Canon SX120 IS isn't listed in the guide. If you want to go Canon, I'd recommend the SD4500 IS. It's smaller and it has Canon's best compact camera image quality technology.

I hope that helps. If you're really into the S8100, I say just get it. But if you look through our pocket superzoom guide and come up with more questions, please don't hesitate to ask. I'll make sure you get the answers you need
