I'm looking at getting the Bachmann Train Set #00501 Digital Commander after a 40yr absence of trains.  I am looking at this set for two reasons (1) its DCC if I read it correctly and (2) its at a beginner price.  I am looking at buying enough extra track to replicate a John Allen "Timesaver" layout instead of an oval.

My question is "Am I getting the right set?".  Cost is a consideration and at my house space is at a premium.

Thanks for any help in advance
