Try to get the smallest one you can find.
I just got a Cannon SD400.
My SD330 broke and Cannon sent me this SD400 one for free.
(even after my warentee had run out)
Smaller than a pack of playing cards.
It takes great pictures close up, or far away,
and has a "digital Macro" feature for detailed part numbers.
And it fits right in my pocket. Takes movies too!!
The size is just as important to me as the quality.
I can walk around anywhere and always have it with me.
Has 3 resolution settings for quality.
The best is absoutly amazing, but I have no need for that setting.
The lowest setting takes great pictures, and they send fast by email.
Cost is around $350
