Don't know anything about it, but a glance at their fees was enough to put me off. $29 a month membership fees?, $25 per year per retirement account? $30 wire transfer fee (that's double anything I ever paid for a wire).
No thanks, seems a tad rich for me.
But, I'm happy with owning individuals stocks and many are not, and this sort of seems like something slightly below holding individual stocks while not exactly being a mutual fund. Plus it looks like there is some sort of hand holding that goes on as well. It might be a good idea for some folks, but I would do my best not to incur too many of their fees.
