Hi Ian,
I own both the CFR handtool and the new Drimaster. In my opinion the new Drimaster wins every time, although be prepared to use a lot of solution (say 50-60 litres for a 3 piece), I run it from my portable with the pressure turned down to around 100 psi, and with the flow control on the handtool set to about halfway.
Having said that the CFR is a good bit of kit also, and is much cheaper. The Drimaster leaves the upholstery much drier though, and there is no need for a second pass (except on edges), so it enables you to work faster and smarter.
