With a D3000 he doesn't need anything heavy duty but if the D3000 was meant to be a gateway to a higher end DSLR then I would buy something a little better than what you'd need with a D3000. A tripod is an investment and I'm a firm believer that you will likely buy a minimum of two tripods until you realize that you just need to get one that will be with you for a very very long time. With that being said, if you're toting a P&S then I'd get something decent, something that supports double the weight of the camera and if a higher end DSLR is purchased then make the investment into a decent tripod.
