NSTableView vs MBTableGrid - the verdict

I have spent some time looking at NSTableView and also the open source MBTableGrid. What I have been doing is playing around with them in test applications to try and get a measure of the two approaches. In the end I have decided to write my own view from the ground up. Looking at the MBTableGrid example has given em a really good idea of what it will take to do it - and the work will not be greater from what I will need to do to get MBTableGrid customized and wrinkled into the form that I need. MBTableGrid is closer to what I need than NSTableView.
