Heheh... I know the feeling. The only reason i mentioned anything is that i went with the s300 solely because it had a 3x zoom, while the s110 had the 2x. I tried 4 times to go to a store to compare them side by side, but every store i went to either had one or the other. I didn't realize the size difference until i had it in hand and got to put it next to my friends s110. The issue for me was pocketability. You notice the s300 bulging in your pocket (it's still WAY smaller than any others i've handled though) but the s110 fits perfectly and i could barely notice it. That's about it.

Not sure if you've checked there for prices... but computers.com has a really good cheap price finder for digi cams. I got mine for 100 less than from any of the big online stores.
