Which Camera SLR do u think is the best and easy to use ?

The Hasselblad H4D-200 would probably be the best dSLR today and it will be a far much better than the Canon 60D but will be much more expensive too. All dSLRs are difficult to use if you don't know the basic principles of photography. All dSLRs are basically the same. If you know how to use one, you can use them all.
