The popular advice specially on HN is to go with low cost Index Funds primarily provided by Vanguard. I personally prefer Fidelity and their low cost Index funds which are FUSEX and FUSVX. Both have very low expense ratio and their returns have consistently beaten the so called "target date" funds.

If you do use Vanguard, there is VFINX that is similar.

The reason index funds are so popular is because they consistently beat the other high cost mutual funds and their costs/fee are much lower.
