Desk suggestions

When I have the time, I'm going tobe building a new desk for my music/everything room.
1) Current desk is low (30") so that the computer keyboard is at a good height for typing. I've seen many people use a slightly higher desk (33-34") with a keyboard drawer - is there any real advantage? I rarely DON'T need the keyboard right in front of me, and having it pull out would mean my monitor needs to be closer to the front of the desk (or the desk is more shallow). A higher desk is good when accessing while standing up which I'm doing when vocal recording.
2) Legs/feet. I've seen any number of mixng desks that use a 'Z' style leg, so that the front support slopes towards the rear (giving more knee room), then the 'foot' sticks out towards the desk front. This is how my portable keyboard stand is made and I'm constantly hitting my (bare) toes on the foot - I don't like this design! Other than a straight up leg, or a front shelf, any ideas? I don't think wall-mounted brackets will be stable enough for a 30" (maybe 36"?) deep desk.
