Just as another data point, a friend of mine who runs a one-man signmaking business recently bought one of these, although his had a T-slot rather than vacuum bed. He found Acctek pretty good to work with; he agreed a spec for the machine via Skype, and he received exactly what he had specified. Cast iron and steel frame, ballscrews, profile rails, water-cooled 2.2KW spindle, USB interface to Mach3. It's Chinese: there are more than a few rough edges, and it needed a little bit of work to get it set up and running (things like a limit switch trigger had come loose and needed readjustment). He used a UK-based shipping agent to handle collection and delivery, and the whole thing cost around £3K. Would have been less but the Brexit vote happened during negotiations and the pound slumped. However, from his point of view, it saved a lot of time in building his own, and to be honest did not cost that much more than buying decent components would have cost. It's not the greatest machine on the planet but it's installed, working, and easily earning its keep. It mainly does text engraving on signs, and is also used for cutting hinge and lock recesses, joints for noticeboard cabinets, things like that.
