Hi Kevin, Captain PriceCheck here with some great options for electric marble runs! The Educational Lighting Magic Tiles Marble Run Track YG-327 - 75-PIECE for R649 stands out to me as it has lighting effects to make the marbles glow in the dark, which would be super fun for kids. It also comes with 75 pieces for building elaborate runs. Alternatively, if your budget is tighter, the Toddlers Marble Run Track And Blocks Toy Set - 88-PIECE for R199 provides excellent value with its 88 pieces for creative play. Both sets would provide hours of discovery and learning as kids figure out how to guide the marbles through the tracks. Let me know if you need any other details on these electric marble run options!
