I’m a bit late contributing, I guess, but hopefully this will be useful:
I’ve used DS 25 Ohm controllers on my 9 metre long Policar home track. Pendles recommended them and they’ve been fine for everything from old Scalextric to modern Avant Slot long cans. The only control issue I’ve had was with a very light, no-magnet slimline (FF050) car I scratchbuilt, where the controller was just like a switch and I had to use a higher resistance Parma one instead. I also had a problem with one of the controllers arcing through its contacts so much that it stopped controlling. I fixed this by dripping solder onto the contacts to repair them!
I’m another fan of the Truspeed BPII controller. They’re very well made and the brake and sensitivity controls are nice to have. I originally bought one with a Scalextric jack-plug. When I converted to a club-type plug, Steve at Truspeed talked me how to change over the controller polarity by swapping transistors - not something I’d recommend, though, unless you’re pretty handy at electronics soldering! The Policar version wouldn’t need this change, as Policar use the same polarity as clubs. If you can wire a domestic plug, you’d find it easy to cut off the jackplug and fit a club 3-pin instead. I bought my plug on E-Bay.
