I've got the Clarke one from Machine Mart for about £120. Yes it's noisy, and dusty. Need all the PPE! But with the hoover connected it's not too bad As others have said I would never use it in an occupied house but in refurbs it has saved me loads of time. Makes a perfectly clean cut - you don't risk damaging surrounding plaster. Nice an easy to slip conduit into the chase too. If you select the correct blade width it holds in place without the need for further fixings. The motor is quite powerful and I'm still on the original blades after about half a dozen full renovations. For me this was the compromise option.
