>Absolutely SSIS. You can test each line as it comes it, do a select against the back end to see if the record already exists, deal with embedded commas etc and funnel those that fail that test to a different table. What's more you can direct the successful output to a staging table for final approval. Very flexible, very tweakable, very easy to learn.
