You really should do your own research on this -- it's your data, why  
trust me to advise you on whether a given cipher will adequately  
protect it?

Blowfish is (last I heard) a well-respected cipher with no known  
ciphertext attacks when running in CBC mode.  It was runner-up to  
Rijndael in the AES competition.  It's been a few years since I was  
really hip to the crypto scene, though, so don't take my word.  See  
above :)
