separate change table or a 2 in 1 dresser?

Hi, I am about to purchase my nursery furniture and just want to make sure I am making right decision. I am looking at a separate change table (with the two shelves underneath). I have been told by a couple friends they are great as you put all your Changjng items (wipes nappies creams etc) on the shelf to reach down and grab. It also leaves the top of the dresser available for some decorative items/lamp etc. 
if I had a huge room I would be sweet with going ahead with that purchase, but it's a small room so I'm wondering if i am better off having change table and dresser combined. 
What are your thoughts?
