They want $3000 minimum grand to start up a brokerage account.
I use Vanguard as well and love them. Low cost funds are huge as another poster brought up, plus I think their app/website/tax documents are very user friendly. BTW, most of their mutual funds require a $3,000 minimum investment, but only require $100 for additional investments. Since mutual funds aren't actively traded, you're only allowed to buy/sell shares of a fund once per month. Not sure what your plan is, but those are a couple of things to think about.
