I just did an outside handle, inside handle, lock actuator and greased the window guides on a window. It takes a little time, but all you need is a small ratchet set and a couple screw drivers. You'll also need a basic drill to drill out the old rivets and you can either buy a hand riveter or use screws in place of the new rivets. Very easy, but giant/fat hands will be your worst enemy. I had to reach up inside the door several times, and space is somewhat limited.
