I recently got a sony wx1. Got it off ebay for like 180 w/ shipping. Its pretty awesome, video is reasonable and allows zooming. Pics are universally good, night photography in particular though not dslr quality. If yellowstone is your destination then scenery pics are in your future. I took these (picasaweb.google.com)on my sony while climbing rainier.... well I took most of them some are from my dad.
