Len are you looking old-school?

I had a TYCO set and was easier to assemble/change than the Aurora tracks with pins if I remember correctly.The Aurora cars worked on it and were maybe faster with better contacts than the tyco brushes..
I looked around on ebay and this looks pretty cool to me and not that much $.

Thanks for the memory of grammer school,trading/flipping baseball cards,HO cars/parts and firecrackers.
