Grad NDs really aren't necessary for digital photography. They were important for scenic shots on film, but with digital there are several post-processing techniques that do a much better job than a Grad ND ever could. And with Grad ND, there's really no choice but to get the oversize, rectangular type (most of which are optical plastic so are rather easily damaged, aren't multi-coated... and harder to store and carry around, difficult to shade well with any sort of lens hood).
Speaking as a landscape photographer this characterization of Grad ND filters couldn't be farther from the truth. I can only assume the poster has been frightened away by the care and setup needed to use them properly. If post processing is so much better than a Grad ND why isn't it better that any Solid ND? The high dynamic range issues of sunrises and sunsets as an example can be balanced with Grad ND's and eliminate the need for post processing. No bracketed images needed. All ND filter manufactures tout Grad ND filters and offer videos on their web sites. Singh-Ray highlights 76 recognizable pros that use their Grads. If the OP wants to do landscape work Grad ND's will serve him or her well and become indispensable.
