Click here for an interesting article on Spanish Sufis. However, I would say there are many more Sufis than the 1,200 mentioned in the article, including many who are not Naqshabandis. For instance, all the Moroccans and Senegalese immigrants must include a number of Shadhulis, Qadiris, Tijanis and others.
