+1 my new martin DX1 came with them when I bought it in january, and I haven't had to change strings at all yet after 6 months. with my old acoustic I used dean markley blue steel strings which weren't nearly as good.

Either the Elixer Nanoweb Phosphor Bronze mentioned by timmy above, or D'Addario EJ16 Phosphor Bronze. Both sound sweet to my ears. Another nice set is the Martin Silk and Steels. Great tuning stability and perfect for recording/studio use.
