Hi there:
I ended up looking for the perfect desk for our home office for so long that I ended up having to make one that works just right. There was a New Yankee Workshop on TV many years ago in which I recall Norm making one very similar to what I ended up making. Links to pics are here:

Best recommendations I can offer are to make sure that you consider what you are going to be doing at the desk. If you have a computer desk at work/school you like the setup of, take a tape measure to it and check out how high the desktop is, the keyboard tray is, and how deep the monitor should be. Also take a tape measure to the chair you will be using to make sure that your knees will clear well below the top or apron of the table.
I'm not sure how the links above will post, so apologies in advance if I really screw something up here.
