Nice black dress shoes?

I'm searching for a nice pair of black dress shoes. I guess I need another pair of black heels. I tried on a bunch in TJ Maxx yesterday and couldn't find anything. The thing is, my coordination skills lead something to be desired. :) I'm a girly-girl and everything, but I can't walk in heels. But I need something to wear with my dresses. I'd rather just wear boots or Converse, but sometimes I have to look like a grown-up. I really don't like ballet flats... it's very hard to find a pair that fits. I have one pair of black heels. They're Oxfords with a chunky sort of heel. Does anyone have any reccommendations for me on what to buy and where to find them?
