We got an ex commercial gym Startrak for about 700....
Cheers mate. I went with a second hand Jet300 for £300.
Used it and its decent enough. Needed a folding one due to space by the rack so whatever I bought was not gonna be commercial level due to that pre-requisite.
when I move to another house (3-5 years), I'm gonna buy one of those massive fixed ones.. I think Nordic do one.. the ones with a CRAZY incline.
