The D7000 is hardly an entry level camera....
It's really not a good first camera for most people.
I really don't see the logic in this statement. Any of the modern digital single lens reflex cameras are as easy to use as any other. They nearly all have program modes, aperture or shutter priority, and manual. Nearly all of them offer variable iso and white balance, regardless if top of the range or cheapest of the offerings.
A D7000 is no harder to use than a D3100. In some ways, the D7000 might even be a better choice for a novice photographer. The focus mechanism is better, the viewfinder is better, it can take older lenses, it will meter with nearly any lense you can manage to mount on it. So what's the problem? How many times have we seen posts on here from photographers wanting to upgrade after only a short time with the base model? Heck why not go to top of the range if can afford it? So you discover you don't like creating images or you would rather have a p$s or mirror-less or bridge instead, you'll be able to resell your 'better than basic' camera pretty quickly and nearly for the purchase price to any of those other beginners who outgrew their entry level box.
