First and foremost, anything nikon since it would likely work with your camera.
Other than that, sigma, tamaron, other major names. If I were you, I'd just go over everything you get in and Ebay/web search things. Odds are you're going to get abunch of generic/casual gear in, but just check the value and resell. I don't think you'll get many modern lenses coming through, so if you do end up with things that mount on your D90 you'll have to use manual focus. It's a nice camera, I started with a D50.
Keep eyes out for point and shoot 35mm cameras. Yashica, Contax, Olympus, etc can be worth a lot of money without looking flashy or expensive. Hook me up with anything Contax or Stylus Epics you find. Thx bby.
