I'm hoping someone might read this and be able to share a similar experience. My DVX100b was purchased in May 2007. In May 2008 I began getting the dreaded SReel Lock error. I searched many forums and although there were lots of instances of this problem, nobody seemed to have a definitive answer. I took my camera in and they want $690 to replace the whole tape transport mechanism. The camera has 560 hours on the head, has been babied and only used by me. Is this acceptable?
