@tdcadillac - if you’re looking for a good example of an entry level smart trainer that does everything you’ll need for Zwift, this would be a good place to start:

I don’t think you’ll get anything better for a £300 budget but feel free to post anything you find if you want someone to give some feedback.
This won’t be as accurate as a power meter or high end trainer, so if that’s important to you don’t go for any wheel on trainer. Go Tacx Neo or Wahoo Kickr.
My journey has been to buy an entry level wheel on turbo (Tacx flow - now discontinued) and recently spent £200 on an accurate power meter which can be used inside and outside. For anyone on a budget this is a nice option because it’s not a huge upfront cost on an entry level smart turbo but can be improved later (again without too much cost) if you do get serious.
