Tom,

Take your wife our to a Camera store or one of the Big Electronic chains that have multiple cameras on display.  Only way to know what fits is to try them out. 

Just some things to consider -

• Some cameras can use regular/rechargeable (AA) batteries - others the more costly Lithium Ion type.  (although you can now get cheap 3rd party versions for most cameras)
• Some cams have a glass viewfinder and other use electronic/LCD (Pivoting LCD is a added plus for different POV shooting (no need to get down on the ground)
• Most cameras have video capability (if thats important to you personally)
• Those classified as SuperZooms cover a good optical range and theres no need to invest in additional lenses.

Since Christmas is coming...I can almost guarantee major sales incentives on cameras...especially around Black Friday...might be good to wait and possible save some cash. If you do find something and buy...be sure to get a GIFT receipt....so it can be returned if needed.
