Which books of Clive cussler to buy? are they good.?

I liked Corsair and The Silent Sea. The Navigator was pretty good. My favorite is Spartan Gold which is the first book in his new series. I tend to like his books that feature Kurt Austin, The Oregon, or Sam and Remi Fargo more than the ones that feature Dirk Pitt. I didn't care for "The Wrecker" at all.
