SV,
I do have Vanguard funds. I just looked up mine and don't have VTFX. I did go to a financial planner just go get a clear understanding of diversification et al. We do buy ourselves on vanguard.com. It is quite straight forward and I do get to see all the funds in one place, I don't think you need a broker if you know what you are buying.
Right now, most funds I own in the US markets is in the negative

which is quite understandable given the current markets. I think the only fund that is staying at 0% is the emerging markets fund(Vanguard).
(***Added)Looks like REIT/Bond funds are the only ones doing ok(vanguard IRA).
Btw, what is the minimum purchase value for VTFX. I've always felt the minimum purchase value for VG funds are not small amounts of money. That was the reason we went to a planner in the first place, to make sure the funds were right keeping in mind my investment goals.
