LOL I almost bought the red one the other day just because it is soooo cool!

I've got a Nikon d7000 and love it.

The red one is a great entry level DSLR. But when buying a DSLR lots of people find themselves getting a bit obsessed and upgrading within a short timeframe so maybe consider if you should go the next step up to start with.

I know you see loads of deals with a camera and two lenses package but maybe consider getting a more expensive body and one general purpose lense to start with - you can always add more lenses later if you find you need them.

Dpreview has some great articles on lenses explaining the differences as well as a great comparison function if you have narrowed your search down.

But having said all that, go into a shop and see how they feel in your hand.

ETA - I have a friend who teaches classes and says that normally about 2/3 of the class have Cannons but he also says you get more bang for your buck with Nikon.
