Hi PhilRMK,
Welcome to the forum
For good general operation and size of decoder the 2 function TCSM1 is a good choice NMRA though a little more than some decoders i use them all the time for installs where a hard wired decoder is called for.

they have a goof proof warranty and either TCS will replace them free of charge or Bromsgrove will replace them if purchased from Bromsgrove models in both cases the buyer pays postage for return of the decoder usually fist class covers it in the U.K.
