Since I was called out here <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

The old repair facility of ETBass in Roosendaal in the Netherlands no longer exists.
However, there are two now, namely one in Bergen op Zoom, which is very good reportedly, acoording to several people I know, and most recently I used the facility in Nederweert, which is relatively close to, e.g., Mönchengladbach in Germany, and which is the second repair point in the Netherlands, and seems to work together with them (and is owned by DSP in Mönchengladbach).
I recently had occasion to work with them, and was very pleased by the very good service they provided. The waiting time despite parts not being in stock was incredibly short, I think (I was quoted a month and it only took a week and a half), but do keep in mind that I am a CPS gold member, so I do happen to be fortunate enough to get some preferential treatment. Not only were they very professional over the phone (to make an appointment - I prefer to deliver and collect myself), but also over the counter, and they emailed me several times to keep me up-to-date, and did phone me to ask, again, whether I didn't want a lens in exchange for the duration of the repair (which would have been sent to me from Germany, BTW). Since I had planned the repair to coincide with a period of inactivity of the lens in question (it could still be used without a problem), I didn't want to go through the hassle of returning a lens by delivery service, so I declined (both times I was asked <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

Just in case somebody wants to know about the repair: the friction mechanism of the 100-400L. I gave it to someone to try out, while the friction was set to maximum, and he managed to zoom regardless. Something in the mechanism gave, so it wouldn't tighten up anymore. The lens could still be used, but I had to be a bit more careful with it as a result. It appeared that the entire focusing ring unit had to be replaced, and that particular part was not in stock.
Anyway, good experience, quick and good repair too. The lens looks like new again.
Kind regards, Wim
