legion07: You didn't mention if you have other lenses, if so, just stick with that company. Lenses are going to be your most expensive accessory. Get the camera that you are familiar with, within a company the cameras more or less operate approximately the same.
IF you are going with Nikon, try their factory refurbished equipment, most of them is new or like new, you can save bunches of money. This equipment comes to you in a plain box with none of the colorful graphics and a 90-day instead of 1-year warranty. I have bought quite a bit of refurb'd Nikon equipment and I have never needed to use their 90-day or 1-year warranty.
ETA: If you feel squeamish of refurb'd equipment, B&H & Adorama will sell you extended warranty for nominal cost. Also stick with places like B&H or Adorama because they will take back their equipment if you don't like it. I have never returned anything, but they say you could. But be aware, they may charge you a restocking fee, so choose wisely.
Canon owns ~50% of the camera market, Nikon ~20%, Sony ~15%, and the balance goes to Panasonic, Olympus, Pentax etc.
