Does anyone have any recommendations for good quality Marble Run toys. My 3 yr old DS loves the quadrilla ones in the store, but he's already getting Magnatiles, so if I go with quadrilla, he'll get the basic one like this one:

Any input on this and other brands? Do you think this set would be too basic?
Thanks!
