what does the B$ community think of target date mutual funds? I'm not a big believer in actively-managed mutual funds, especially with so many cheaper ETFs out there, and I like the automatic asset allocation. but I've also read that it's not the most tax-efficient, e.g. if it has tax-exempt bond holdings and you have the fund in a tax-deferred account. granted, this is probably not much of an issue for e.g. a 2050 fund that has minimal bond holdings, but something to think about.
one reason I'm thinking about this is that I was looking at my 401k and realized I really never did much research into my fund choices. I also didn't realize there was a "fund window" that allowed me to buy a whole bunch of other funds, including a couple target funds. weird thing is, they offer fidelity's target funds, but with a "max front-end sales load" of 5.75%

why would anyone pay any load for a fund that essentially tracks the S&P 500? am I crazy or is this ridiculous, even for an actively managed fund?
I could also choose a few vanguard funds, but they don't offer vanguard's target date funds, nor do they offer enough of their individual funds for me to synthetically construct it.
