If costs are on your mind as you consider whether to invest, then you might want to consider Vanguard as your frontrunner. Vanguard is an established mutual fund broker dealing with income funds and various other accounts. You won't pay any commissions for investing in Vanguard funds, while non-Vanguard and select funds require commission fees of no more than $35. If you plan on investing over the long haul -- or if you simply want to minimize risk as you get into the stock market -- then Vanguard is a great place to put your money. On the other hand, if you're an active trader with more knowledge about the workings of the stock market, then another firm might be better-suited for your skill set. Consider Vanguard though if your priority is investing in long-term, slow-growth income and mutual funds.
