Servo query

[Sumilidon]

Hello all,

My servo is some 20 years old and although it works well, I'm not sure if there are are real benefits to a more modern servo (eg digital).

Budget is ot much £15 quid really and ot sure what to look for. It will be used on an xray t2 touring car (which I am also awaiting spacers as the servo rubs against the drive belt on full steer)

Suggestions welcomed
