Going to throw my hat into the “Tacx Neo 1 is super-solid and totally worth it” ring.
It’s built like a frigging tank, has never given me a single problem, is responsive enough (though it really could be more responsive for 15 second microbursts, as I have to sort of trick it, now, using cadence) and it’s absolutely been worth it.
That being said, Garmin has always been a sh-tty company and I occasionally want to throw my Edge 820 off of a mountain; their products are overpriced, their UI is garbage, and when they fail they fail badly. I do not forsee good things for the Tacx product line, in the future, and their whole “Legacy product? lol get bent” response is right up their alley.
So, on balance, it’s kind of a toss up. If the price you are seeing undercuts the competition (Cyclops, Elite, Wahoo, etc) by quite a lot, it’s probably worth it. Just don’t upgrade the firmware (I haven’t and have had no problems) and be aware that Garmin has yet to solidify its position on supporting Neo 1s – they could very well say “Yeah, we thought about it and you can all get fscked lol here’s a pitiful discount off a more expensive trainer”
