Index fund decision: Vanguard or Fidelity Target Retirement

[DeathDonkey]

OK, I have my SE 401(k) through Fidelity, Vanguard does not offer what I wanted. I have a Roth IRA through Vanguard and own their Target 2045 Retirement Index Fund and am very happy with that and to leave the decisions out of my hands.

I just contributed my 2006 amount to my new Fidelity 401(k) and now need to decide what to invest it in: I can invest it for no upfront fees in Fidelity's Freedom 2045 Fund (FFFGX). It has an expense ratio of ~0.70%. Alternatively, I can invest in Vanguard's Target Retirement 2045 Fund (VTIVX) which has an expense ratio of 0.21% but I must pay a $75 online processing fee.

I am very new to this stuff, but the Vanguard one seems clearly better looking at the difference in expense ratios for only a $75 fee, I think I should go with that one. Just wanted to check here to make sure my thought process is sound and if anyone knows of a good reason to prefer one of these target retirement funds over the other I'd love to hear it.

Thank you,
