I just ordered my DR from B&H, also the 28-135 IS lens (around $400). I read many reviews and asked many folks about the right lens for my purposes (hate tripods). I'll let you know how I like it when it gets here, although many folks here do seem to like it.
I'm also wanting a prime lens 50mm 1.8 for low light situations. I honestly don't know if you'll be able to find exactly what you want that's within your budget. Good luck and let us know what you decide.
