I  have  a  Dynamis  system which  is  not  used  primarily  for   my  G  scale  locos  BUT
       I  did  try  it  out  of  curiosity  and  I  was  surprised  to  find  that it  worked  jsut  as  well  as  my  MTS system... granted  I did not   run  more  than  2  locos  at  a  time,  However  I  dont  usually run  more  than  2  with  the  MTS!!
      
     I also found that   I  had  no  problems  using  the  dynamis to    programe  the  loco  decoders,  I did not  experience  any  problems  with  LGB  factory  fitted  decoders,  ones  tha  I  had  fitted  myself  or  Massoth  decoders
      
     But  I  personally  would  not  rely on  the  Dynamis  for    everyday  running  of  a  garden line,  as  the  infra  red  communication  is  not 100% reliable outdoors,  it  is  possible  to  upgrade  the  system  to  a  RADIO control   system but  that  adds  to  the  cost.
      
     Personally  I  would  recommend   MTS  or  Massoth  ( but  of  course  these  are  expensive) there  are  quite  a  few  being  offered on  the  S/H  market currently  as    some  G  scalers  seem  to be  selling  up!,
