I don't cut a lot of fondant, and I don't expect to in the future, but I like the fondant cutters from Cake Boss for making cute bite-size cookies. I tested the dinosaur cutters ($9.99) with a basic roll-out cookie recipe and was really pleased with the results. The cutters cut smoothly, the embossing works, and you just press the knob to eject the cookies.
The T-Rex was the bulkiest of the bunch, but still only about 2 1/4 inches from nose to tail—think the size of animal crackers. The brontosaurus was the slimmest, but a little longer at 2 1/2 inches. Three of the four cookies in the set were able to stand on their own when I made them thick enough. T-Rex was posed on one foot, so he didn't stand, but he did a fine job leaning.
Besides the dinosaur set, there's a springtime set, a princess set, and work truck set, each with four cutters.
I'm not seeing a downside to these, as long as you're happy with the size of the cookies. And of course, you can use these for cutting fondant or pastry or anything else you can think of.
