Every deadbolt has its strengths and weaknesses. In a cylindrical deadbolt, I like to see a good, strong, positively locking bolt, a cowl that protects the inner locking mechanism and a cylinder that offers at least some protection against picking and bumping. My recommendations would be the Medeco Maxum deadbolt, and the Schlage B660 in one of their Everest keyways. For a surface mounted deadbolt, I recommend the Segal 666 or 667 drop bolt. I have seen the Segal used with the Medeco Maxum on a hollow metal door resist attack pretty well.
The bottom line is always, however, that whatever can be put on with tools can be taken off with tools. All a good lock can really do is slow a burglar down. Burglars do not want to spend a lot of time breaking in. So, if you can make it difficult, they may either give up before getting in, or look for an easier door to break into.
