Lenz LH100 throttle with a LZV100 command station, had it for over 10 years, it's worked perfectly for over 21 show in that time. It has been updated recently by A & H Models (great customer service by the way), and has just completed the one day show of the Gauge O Guild at Doncaster with no problems with upto 10 twin motor Heljan O gauge diesels with sound on the layout at the same time ticking over!
