I am sure this is a good service but actually you cannot count it as being 100% reliable. The reason for this is that the contactless system only employs one sensor, whereas the original has two and the ECU makes a comparison between them. Ex-modex in the states operates a similar service to Lucus and these have been known to fail/give rise to problems too. Out of interest, what did it cost? Ex-modex is north of $500 but very quick about two days I think (send away - remanufacture). The new Bosh replacement for the original Megnetti Marelli is also contactless.
Some people change the unit themselves before it gives trouble. Here is one source of the part.

I ducked out when I recently serviced my PCV system, because it requires fine soldering old (possibly corroded) contacts and my unit was replaced 18 months ago.
