I wanted to get on Zwift before the winter. Of course I wanted a smart trainer, but didn't have 1k laying around for a Kickr, so I got the Performance Comp Fluid for $99 (it lists for $199 but it's almost always on sale for $99-$129). Spending a bunch for a "premium" dumb trainer to get on the Island just didn't make sense.
As it turns out I am impressed with the Performance trainer, it's solid, very smooth (once warmed up) and provides all the resistance I can handle. I really don't think the Zwift experience would be any better with a more expensive dumb trainer.
