Evening,
I've got a Nikon D7000 and it's absolutely brilliant! I bought it about a week after they came out over here, having read some fantastic reviews from the US. I've got a 50mm f/1.8 for low light (£150 from jessops but no doubt cheaper elsewhere) and an 18-200mm f/3.5-5.6 for general day to day use, as well as the MB-D11 battery grip for portrait shots.
I've still got my first DSLR, a Nikon D40x which was good as a starter to get me used to the buttons and functions. I wouldn't give up my D7000 for anything now. It's set up how I need it and it's easy as pie to change settings on the go. The 2 user defined settings are excellent and you can change the shooting modes with a twist of the dial.
I've got some photos from a trip to the zoo yesterday that I can upload if you want to see the picture quality.
The D7000 and 18-200mm combo are perfect for pretty much everything, including some low light due to the vibration reduction built in to the lens. You can also use AF and AF-D lenses with it too, which is an upgrade that wasn't on the d40x. The autofocus is super fast and the battery grip is very useful too (albeit pretty pricey). I believe the battery is a new type of Li-ion batt that lasts a lot longer and helps to keep the continuous shot mode pretty quick too.
I'd very much recommend it. I haven't used the video recording function as I don't have any use for it, but the still photo functions are great! I definitely think it's one of the best purchases I've made in a long time
