These Scholastic Text Messengers can network with up to 24 other units, and provide text message functionality without all that messy payment stuff. Like a walkie talkie for text, but with a max range of just 600 feet. Perfect for the playground only perhaps? The other limitation is the fact that each message can only be 40 characters long, but in these Twitter filled days, that’s probably quite enough. $16.99.
