DES isn't actually broken, however the keylength of 56 bits was deliberately crippled by the US NSA, presumably because they have a backdoor to decrypt it with short keylengths.

3DES is supposedly pretty secure by using a triple pass in chain-block cipher mode.

AES is generally faster and is considered as secure as blowfish. I've not looked at RC6 myself, YMMV.
