QUOTE: Originally posted by JamesT1 With some of the other "entry level" DCC systems such as the Digitrax Zephyr or Lenz Compact (Atlas Commander) there is a much higher level of functionality and at least you can still use them as a booster or throttle if your layout grows. I guess the Roco Lokmouse system is the same - I think it uses the Lenz XpressNet bus system?
