Waffle makers are fantastic and so very versatile. In addition to waffles, you can use them for all sorts of things!
You can make hashbrowns, paninis, fritters (cakes), and waffle cones, among other things!
In all honesty, even if all you ever make are waffles... wouldn't it be worth it?
The only question is, how many waffles would you like to be able to make at one time?
