Split prism in the viewfinder for manual focusing

Recently picked up an old film camera and played around with it.  Then it came back to me, the split prism for manual focusing in the viewfinder...made it easy and accurate to manually focus.

Is there really nothing for the digital DSLR's that can give me this feature back?  I find it almost impossible to manually focus without it and have to rely on the autofocus of my 7D or 50D.  I know I can zoom in the LCD screen but that is timely and not practical always.

I think I've asked this years ago but thought I'd give it another try.
