I've had the Surflex AF cassette clutch (the more expensive £400 one) in my TS1 for a good few years now and had absolutely no issues, given I've ridden well over 15,000 miles using it. I took it apart last winter, when I had the engine apart to check everything was ok, and replace the plates/steels (which cost about £50 in total), but the ones that I took out were still very useable. (I carry them are spares)
I have known the cheaper version not coming up to the same fault free level as the £400 AF clutch, however with clutches it obviously depends a lot on individual riding style. In the time I've had my AF clutch in, some of my riding companions have had 2 or 3 different clutches/clutch rebuilds in their TS1.
The best advice is always to go for what you can afford.
