You can find MUCH cheaper helis, and perhaps smaller:
This one is only 6 grams:
And this one is only 9.5 grams, and $9.95:
I purchased 5 of the $9.95 helis, and gave some away as fun gifts. They actually fly great for what they are! You can get a good hover going and land where you want when you get a good feel for the controls. It's fun taking off from your fingers, then catching it when you bring it back!
