I have loved fischertechnik since I was 7, and I'm now 44. Personally I think it offers a vastly better experience, especially per-kit, than competing kits. When I found out these kits were still available, but in updated form, I was super excited. This kit in particular is amazing. Don't hesitate, just buy it, and keep track of the parts and the book. If you do, the kit will be useful for at least a generation.
