I am looking at a scope from cdnn.  The tar29 and the tar52.  Anyone have any experience with this company and these scopes.

Ditto.  I have bought a lot from them and they are a real good company.  However, they also sell some pretty low quality items so do your homework before buying the scope.  I know nothing of the scopes you mention.

I just ordered a carry handle from them on Thursday (Oct. 14) I got it today (Monday). They sent it priority mail. The customer service I recieved was excellent. I had questions about the rear site on the carry handle. They had one there in their office. It is exactly as they described it. I am very happy with the handle and their customer service. As far as optics, I do not know. I usually want to have the scope in my hand to be sure it is what I want, (but that is just me). I hope this helps.
