I love my Professor Motor baseline controller. It can be upgraded at a later date to variable braking and adjustable sensitivity. However, I rewired my track and dropped in a variable lab power supply. Best investment ever made and it will move with me to a bigger track if I ever find the room. I ditched the Scalex power track and wired the supply direct to track (with inline fuses included) and went for the PM2120 instead of the PM2113. Note, the rewiring means my track now runs the same as most commercial tracks (positive wiring rather than the negative of standard Scalex) and I can take my controller with me if I go elsewhere.

Instructions for wiring track can be found at Fergy's Place.

The variable power supply is possibly the very best investment you can make if you have kids using your track.
