Thanks for the Personal Capital suggestion. It does seem like a very nice interface, but my 401K is not accessible with them. I have put in a request to have it added, has anyone had much success with this?
I've never had a problem with loading any of my accounts into personal capital, but I've had a couple of minor issues that they have addressed. One issue was with my 401k through prudential from my former employer's plan. The account and the holdings loaded fine for a while, then suddenly all the investments showed up as being invested in just one fund. As it turns out, they changed the interface at prudential from straight html to flash based, which made it impossible for personal capital to pull the data from prudential. I sent a service request and they eventually fixed it so my holdings show up correctly now.
From my work on IT projects, I know this is how bugs are often discovered (we're all beta testers, after all!). They don't know there's a problem until a user reports a problem. I think asking them to hook up to your 401k is reasonable, and I'm sure they will get to it eventually. FYI, it sometimes took them a week or more to respond to my requests, so be patient!
