I have a KK Road Machine and use it a lot for the past 10 years. It's been great. At the increased price of the RR I would look at a smart trainer. The software is getting better and the prices are starting to come down a bit. I could have gotten a Wahoo Kicker for Christmas but passed because the cost/reward over the Road Machine wasn't worth it. When I need a new smart phone (mine doesn't want to die) I will get the KK Inride pod for $75 which is recognized as a power meter selection on Trainerroad and has a calibration spin-down feature. Try out the RR and the Road Machine to see if the difference in cost feels worth it to you.
