Here's mine:
                                                                                                          

Top one is is a cheap basic model just for tyre truer and motor running in.
Bottom ones are the track supply and an eBay bargain - £50 the pair all in. I think they are pushing £100 each retail. They are 2.5 amp regulated, more than ample for the cars I run. One for each lane so I can hot wire a plug and run a ghost car. They also have separate 12v and 5v connections for the lightbridge and pit garage lighting.
