Greetings.
Heres a good topic for my first post
The subject of starter sets always crops up somewhere, so I would like to give you my own personal experience that I am very happy with.
The world of DCC is full of technospeak and confusion.. ie its a huge learning curve. As you progress, it all seems to fall into place.
I spent a year working through this same problem, and my route was.. I started with an Atlas Commander. Although only capable of 2 digit addressing and functions 0-4 being available, its simplicity and ease of use was to me paramount. Sometime after this initial purchase, I added an Atlas Handheld and a Lenz XPA adapter and cordless phone as additional throttles. This system worked great.
Lately I have upgraded to a lenz 100. The major decision for this route is that by continuing with 2 digit addressing (I doubt I will get to over 100 locos on the layout.. its not big enough

), I can use my Atlas commander and handheld as additional throttles. Since the Atlas Commander is made by lenz, all the units work together as a complete unit very well.
Currently I have a Lenz 100, Atlas commander (as slave), Atlas Handheld and XPA with an Li101 computer interface to link everything to the computer and my CTI control system.
As always, I believe the benefit of all this was baby steps, one after the other and remaining happy at each stage without getting overwhelmed at any point in the whole process with technobabble and confusion and without having to make any previous purchase redundant and sacrifice the cost.
I assume, although I wouldn't know, that a similar route could be taken with a digitrax zephyr and then adding to that if you wished to play the Digitrax route.
As usual, I have no connection with any manufacturers, just a very satisfied user.
