I definitely don't think it should be a delete, in fact I think it should be renamed to the original Samsung NV100HD. The first line of the summary can be explicit about its relationship with the TL34HD, but if you think about the way people search, they are likely to search for only the product name they know, not that it's a duplicate of another named product. This is similar to Wikipedia's disambiguation policy, instead of having a dedicated disambiguation page, we just have both products listed.
