The Next Day Blinds plantation shutters we had broke often. They were good about sending someone out to fix them, but it was still annoying to schedule an appointment and wait around for the repair. One of the repair guys they sent was totally creepy.
Based on the recommendation of someone on this site, we used Perfect Fit Shutters when we moved into our new house,
http://perfectfitshutters.com/. They were very reasonably priced and they did a beautiful job. They even matched the color of our trim (a custom paint). And I've had no problems with blinds breaking or coming loose like I did with NDB.
