Believe it or not.
I told my daughter's $77 Digital Camera Empress from Fry's hiking with me.
Instead of my $3000 Nikon Digital Camera or my wife's $300 Panasonic Digital Camera.

The $77 DCamera uses two AA, in which I replaced with my Lithium AA.
My wife's DC uses a rechargeable Cartridge.
The $3000 Nikon doesn't do Video and too HEAVY.

Plus, I wouldn't cry if I dropped, stepped on, Lost and smashed my daughter's Digital Camera.

You cannot really go wrong with any Digital Camera nowadays.
Just don't buy at a pawn shop, because those are really the older generation cameras.
Anything that is over 5MP is well more than enough for what you need and is of the generation that has no discerning quality differences.
