As a very small ERR dealer, but one who has been doing TMCC conversions since the days of the LCRU scavenged from Lionel locos (Pre-Digital Dynamics, Pre-TAS, And Pre-ERR) mostly for 5 hobby shops located in a rural not too affluent part of Upstate NY, I will say that while I personally prefer the Cruise Commander; the DC Commander has been the choice of my customers almost 2 to 1 because of the price differential. For them the extra $50 per loco is a lot of money. I'm saying this not to start an argument but merely to offer some info from the other side of the coin (pun intended!).
Good input, I guess I push the Cruise Commander pretty hard as I know in the overall price it's not that much more for a significant performance gain.
