Oh I missed the trainer recommendation stuff, I would have wholeheartedly recommended the first gen Hammer. I've had mine 3 years now and it's been life changing, really accurate (verified with other PMs) and huge flywheel. If you can pick up a Hammer for cheap, do it. It's as good as the H3, supposedly less quiet but I don't notice the noise when I have my fans going anyway. Definitely wouldn't trade mine in for anything, my only regret was paying early adopter price of $1200 lol
