seems like some newer members have built some nice tracks using stock wall warts. for those interested in a better power supply, here are some options (better becasue regulated power supplies have no AC ripple which makes DC motors run hotter andd wear out faster and have more amperage; wall warts only supply milliamps).

pyramind PS-32LAB 110/120VAC 60 Hz Input, 0-5A Adjustable Output Current, 0-30V Adjustable Output Power, Short Circuit Protection, Suitable For Scientific & Technical Applications $69.99 (not sure if its regulated, but has lots of amps for stock cars and variable throughout slot car range; i.e., 12-20 volts)
