We had one from IKEA that attached to a top of a chest of drawers, and I loved it. And now the drawers are for clothes and not nappies and wraps and all the associated stuff. I found it really convenient to have everything all in one place. Others do just fine without one. For me, it was the height as well, I really liked being able to stand to change bub.

If you have ample storage space, what about a foldable change table? That'd be fairly cheap, you could move it easily, and you'd still have the convenient height and designated space.

If you don't feel you need one, it's not like you have to have one! I prefer to have a change table/area, but not everyone does. Whatever works for you.
