We have been buying spare parts and accessories from CNN.cn for several years now. They not only have very good prices, their service is also pretty good. I know, I have bought from them.
At any rate, it may be an additional source for parts and accessories in case you’re looking for something and not finding it in other places.
UPDATE: This article was written on Friday, when Lencri.com was still up. We decided to publish it today, on Monday, and it seems that Lencri.com is now undergoing maintenance. That was an unfortunate, unexpected coincidence. I am sorry for the frustration this may cause. Hopefully, their site will be better when it comes back up.
