Thatotherguy84, if you just want to get into ss/fg riding and don't know much about it, go for an IRO or a Surly or Masi or Bianchi Pista or San Jose.
You'll want at least a front brake. A flip-flop hub on the rear wheel so you can ride either singlespeed(able to coast) or fixed(not able to coast).
Drop handlebars offer the most hand positions which keeps your hands from going numb. Bullhorns are another good option. Don't go super narrow with your first handlebars. First, they aren't that comfortable if your arms are squeezing your chest. Second, twitchier to steer.
Frame material matters not. Steel or aluminum; TIG welded. Get chrome-moly steel.
I ride and recommend the Bianchi San Jose. It comes with brakes and a flip-flop hub. Double-butted, heat-treated chromoly steel. Drop handlbars. Can take fenders, racks, bottle cages. I've ridden the heck out of mine, even doing 50+ mile road rides with geared riders. It's a great commuter bike. It's also fast and can be customized easily later as you develop your hipster side.
Right now it's got a rear rack, road slicks and a saddlebag that unclips so I can take it with me if I need to.
