Pre-made modular systems

[Catt]

With those prices I do believe I would build my own.I like the idea of the cam lock but it should not be to hard to figure out how to do them or find plans online to show you how to do the cam lock yourself.The guide pins are a definate plus and will allow running the track to the end of the module thus eliminating fitter tracks which seem to either grow or shrink between set ups.

As for the module joints you can run the scenery right to the edge of the module,plant a building on the joint ,make a road that would simply drop in place over the joint.
