I predicted this way back when this all broke. The whole royalty thing was going to add to the cost. But did not realize ERR was running on 4 year old stock. Once a component goes obsolete and a redesign of the board is required, there will be more sticker shock. I have a feeling, TMCC is going the way of PS-1. Still out their but.....
TMCC is the only way to go for AC motors, but the cost difference on the normal DC Motor steam is going to be a significant jump especially if you want the MTH like smoke features and chuff control with GRJ additions. Sounds like parts alone will be approaching $400 between ERR and GRJ. G
