Yup - I have the Koni top-adjustable inserts on the front, and Koni push-and-twist-to-adjust ones on the rear. I did them myself last year.
The ride is good - possibly a little stiffer than the ones I removed, but they were 18 years/125,000 miles old, so you'd expect them to be a bit loose. The big difference is the handling - it is VERY crisp. (Pushing the fronts up to maximum stiffness made the biggest difference.)
I'd recommend them. BUT the cost of a complete job racks up quickly. Shocks, plus some new bushes (ARB, front and rear, well worth the money), tie-rod ends (possibly not worth the money but I did it anyway), plus a full alignment, and you won't be getting much change from £800. And that's DIY-fitting.
One point to note. They take time to settle, and the first couple of hundred miles feel dreadful. But, after that, they quite suddenly start to feel fantastic. (I think this is common to many suspension kits, as ones I have fitted to other cars did the same.)
Oli.
