Suggestion for a complete DSLR camera package?

Hi,

I have been using the Sony Z-1 for a long time. Although I love how easy it is to use/film with it, I need to update. Any video camera that has the closest look as DSLR? Camera on the range of $3000 to $5000? I looked at the Sony NEX-FS100u, but read some reviews that were not very positive.

Any suggestions for a complete DSLR package?

I do a lot of promotional/corporate/marketing videos. So lots of interviews...

Camera
Lenses
Tripod
Digital Audio Recorder
Camera Hand-held/grip device? (I have the glide cam HD4000)

Any thoughts or direction would be greatly appreciated!

Thanks!
Daniel
