I bought my last domain at Namecheap because they said that they provide a free secondary DNS service for your domains. After I tried to set it up I was informed that you can use their free secondary DNS only for domains that where not bought with namecheap!!! Then I bought GoDaddys premium DNS solution for 35$/year and I use their DNS servers as 3rd and 4th DNS servers for all my domains (primary and secondary are on my servers). This was really the best offer I could find for slave DNS hosting and it works pretty great, even when GoDaddy is down :)
