How is the Replacement AF Motor on Your DA Working?

Posted a query on another thread regarding the longevity of replacement AF motors for Pentax's SDM lenses. The only responses I have received are sympathy replies, which I appreciate. But I am trying to get feedback from folks who have had these motors replaced and whether they sense the replacement motors will last longer. So I am reposting with a more narrow topic.

I have two I need replaced and am debating whether to do it. Perhaps I can call CRIS and talk to someone there in the know as Pentax won't tell me anything.

Boy, all this talk about SDM failure had me going yesterday ...I had the FA 77 limited on my K-7 and replaced it with the DA* 300 for some shots I was taking and the damn thing wouldn't autofocus!!! Turns out I had the camera set to manual focus ...would normally be the first thing I look at, but as I said all this talk about SDM failure got to me.

over one year i had situation: ''SDM died on me'', my 16-50 gone to service at may, i was calling them many times, answer was: we wait for the part from the Japan, at september i got my new lens as replacemen, it was send from Germany with russian manual in the box. The answer to your question, basing on my expirience is: thay wasn't able to fix the lens within 4 months.... they never did
