I hope you like it! It was my first purchased lens and it stays on my camera 90% of the time. If you're interested, another great piece of glass for the money is the 50mm 1.8D for about $100. Exact pricing will vary; I bought mine for $75 used.
It is one you can bring with you to the land of full frames later, but it is a little long on our cropped sensors. Personally, I prefer the 35 since I usually find it easier to get closer than to get further away, but it's still a great lens. Since your D7000 will autofocus with it, the 50D has a much nicer price-quality ratio than the newer, plastic AF-S 50G which rings in at $220 retail.
