I think of Denford and Boxford as separate companies, but I see lathes.co.uk identifies Denford as the parent. Which particular lathe does your friend have?
In general Denford and Boxford lathes have solid reputations. In the heyday of manual machines their offerings were too expensive for all but the richest amateur; now they are available as second-hand bargains.
But buying second-hand condition is everything. Could be the lathe was worn out on a production line, left outside in the rain for 20 years, and all the accessories are missing. At the other extreme it's in brand-new condition. (Friend of mine did a spell as Technician in a Girls' School, where his pristine private workshop contained a Denford CNC lathe. To his knowledge it had never been used, condition perfect and complete. Talk of selling it but he retired first.)
