I know I've asked a couple of individuals about this but thought I'd put this on here.

I'm after a trainer (ASAP) but I've never used one or even seen one in action. I have no idea how to set them up so I'm a real beginner on them.

The only thing I do know is it needs to connect to computer (probably Zwift - purely because that's the only one I've heard off lol)

Finally it needs to be cheap (I'm only a poor Trucker driver lol) 

Any suggestions
