Hi . I am reliving my childhood . So currently I have a R265 controller and a transformer . Great for when I was a kid . But I’m looking for good slow speed control and things have moved on . Can anyone point me in the right direction . I have been told a R8250 but also a Gaugemaster Combi or a H&D unit . Treat me as a kid and give it to me straight . Sorry that should be I have a very old R965 unit . any opinions on the R8250 and R7229 controllers if I stay with Hornby
