We purchased the oiled oak desk.  It is absolutely beautiful.  The directions were easy to follow.  My husband put it together himself in about an hour. It would have taken less time, but he put one of the brackets in incorrectly.  The desk is very sturdy and a beautiful addition to the room.  

Pros: Sturdy, easy to put together, a fantastic value for the quality
Cons: For us, there are no cos.
