More reliable and better control, we (royal, SWTSMBO) have had gaugemaster HH for years using a very old cased transformer as supply, no probs, and with the pot (on the pcb) tweeked the slow running is very good. The boys HAD two Hornby units (one each) and now are using Mum's HH as one's died, my electronics eng. at work took one look and said bin it and he'll build me a better unit for the price of a pint! That said I've recently bought a gaugemaster D twin secondhand for them and Mum can have her HH back.
You might also consider Kentrol if combined fixed and remote ops might be required, havn't used them, but they might be worth a look?
