On Garmin/Tacx support, I think it’s really depended on which side of the pond you were on. For most US folks, Tacx support pre-Garmin generally had high degrees of suck. Now, the vast majority of people I hear from say it’s surprisingly good with people getting parts/answers/etc pretty much instantly.
Inversely, it sounds like Tacx support via some (but not all) Garmin European offices is less than awesome (for example, I’ve heard some non-good UK bits).
As for Garmin buying TR, Garmin is constantly on the lookout for acquisition opportunities. They average one per year in the fitness/outdoor segment. However, the Tacx acquisition is taking a lot of time to fully digest and smooth out behind the scenes. It’s by far the largest/biggest they’ve done in a long time. Prior to that would have been the acquisition of Delorme. Most though are quieter that are supporting tech. For example a solar panel company in France for the Fenix 6X Solar panels, or a Kickstarter project for Varia Radar, and on and on.
An acquisition of TR would be a substantial twist in direction for Garmin Fitness from a revenue standpoint. They offer subscription services for their Outdoor satellite communicators (via Delorme), but that’s about it for recurring revenue, albeit Tacx has some recurring revenue. But in the grand scheme of Garmin revenue the Tacx app paid subs isn’t even a rounding error. I could see how buying TR would be appealing to Garmin on multiple business fronts.
