I'm really impressed with the C750.  I have had a c720 for about a year and a
half.  Very happy with it.  I am restricted in size of my pictures by my
printer (8.5 X 11) and my results so far have been great.

Now! my cousin just gat a c750!  He really piises me off!  I love the all metal
case.  The pics he takes will be 25% better than mine as far as detail goes. 
But is that a real advantage? I think my artistic talent will overcome his
technical advantage!  LOL.   

But the c750 is a great camara!
