Namedrive is definitely good for spanish domains, they offer full support for IDN domains.You can list the domain in Unicode or Punycode and set keywords in Spanish. Landing pages will automatically be shown in spanish (for spanish spoken visitors)
plus, they deliver advertising in every country which Google serves ads in.
