I think this is a really child-specific thing! My ds really liked K'nex for a little while but he moved on to Legos and never looked back. He has a cousin, however, who loved building motorized K'nex structures well into his early teens.

Also in the not-to-distant future you might want to start looking into Lego Robotics kits wink Just thought I'd toss that out there - that was where our ds really liked to bug us to spend the big bucks......................
