Turbo Trainer with Power

I want the power to be pretty accurate

If this is a key criteria, then suggest a Computrainer, probably a Lab model.

I'm not sure how well the Powerbeam Pro goes in the accuracy stakes, I've not seen it used.

Most other "power" turbos don't stack up on the accuracy/repeatability front.

If you use a turbo for the resistance and have a good power meter, then your options are far wider since the meter takes care of the accuracy, even if the turbo resistance drifts/varies. It may still be an issue however if you want the turbo to control the resistance (e.g. riding pre-programmed training sessions) and for that resistance to be consistent.

For indoor trainer accuracy, then dedicated ergo bikes such as Velodyne, Velotron, SRM ergo bike, Cyclops PT300 are the best bet although the latter can suffer from heat drift. They also have the advantage of a sizable flywheel.

For limiting noise, I think the issue will be more the noise of the cooling fan required rather than the trainer.

Cheapest way to reliable power measurement with the added bonus of being able to use it on the road as well would be a PowerTap. Then just get a cheap turbo.
