I don't see a need to. If I had to have another repair done, then I might ask for it to be done, but I would rather not have the camera opened up for something that is really a non-issue. There is always a chance that something could happen while being 'on the bench' that isn't detected until I get it back, requiring me to send it back for another repair. There is an old saying, "if it ain't broke, don't fix it." That sums up how I feel. Maybe if I ever decide to sell it, I'll send it in for a cleaning and have it done then, but I have no intention of selling mine...not for a long time at least.
