This is the first time I have heard ESU decoders being described as 'inferior', the LokPilot Non sound decoder if very good, operates all the featires and is around £15.00 cheaper it would appear!!, did'nt realise Zimo decoders were so expensive. A Legomanbiffo sound decoder is only another £70.00!!!
