The Tacx speedmatic is a low priced magnetic trainer that’s a great option for a first time turbo user. It’s solidly built and fairly quiet, though it requires a bit of time to set up initially.
Once on it, you have a choice of 10 resistance levels plus your own gears, and we found that to be more than enough for any type of training. Roll-down is excellent: we got 17 seconds coasting from a sprint to a stop on the lowest resistance setting. The power curve is quite good, although it does feel a bit easy at the top end.
