I was literally just thinking about buying this toy the other day!
A girlfriend had this toy and when we took the kids to lunch a few weeks ago; she pulled the Magformers set out of her purse for her kids to play with! They looked so cool and the kids played so nicely (i.e. quietly) with them, that I had to find out what the toy was!
Right now at Educents.com you can get this toy for just $34.99!
