I would say if you are buying a quality dirt bike new it would cost anywhere between 2,000-14,000 dollars. Used would probably be anywhere from 500-9,000 dollars. There are more expensive ones but this is for a quality dirt bike, not an extremely professional dirt bike.
And gravel roads. And, of course cross bikes are very good on roads, especially with the right tires. Plenty of nice cross bikes out there, at pretty good prices. A lot of bike for the money can be found in Giant's TCX 1 ($1,700). It's a cross bike with a light aluminum frame and a nifty SRAM Rival component group. It has a compact crank for good climbing, you can add fenders to it, do whatever you want.
