Which entry Level DSLR to buy?

I'm planning to buy an entry level DSLR
preferable Cannon or Nikon. The ones I have identified are

Nikon D3100
Cannon 500D
Cannon 550D
Nikon D5000
I want more value for money.

My interest is in
1> Nature photography
2> Macro
3> Light

Also suggest me lenses for the above.

If you know some good deal available in India or in USA do suggest it to me.

If there's some other camera that i have missed out then do suggest it to me.

If you want more VFM, then go for the Pentax Kx.

Edit.
I see the 'blinkered brigade' are out of school.

Any entry level camera will work for you…

you really should look beyond canikon… Pentax and sony are just as good…

though too many people rave about canikon without any real concept of the rest of the cameras out there…

best thing to do is:
1) go to a camera shop and get the feel for a camera…
2) look at your budget…
3) look at the accessories - cost, availability
4) look at bundles available… Camera body plus kit lenses, etc
5) price up costs of additional items - macro lens for macro photography, etc

Canon 500D or the Nikon 3100 are very good cameras. I would stay in one of those two brands due to the large range of lenses and peripherals available but Sony is pretty good as well as they baught out another company a wehile back and the older companies lenses work with the sony Alpha mount.

I'm a Canon guy myself and would recommend the Xsi or T1i to anyone starting. I'm not so knowledgeable about Nikons but I know quite a few photographers that swear by them as well.

You should get used to your camera before you go out and buy some expensive glass for it. For most things, your kit lens (18-55mm) is a decent learning lens.

For nature, the basic kit lens is fine until you can afford some much better glass. It's good for landscapes. If you want to do wildlife, you'll want something with a bit more range so a 70-200 ro 70-300 isn't a bad choice… Problem is that the GOOD 70-200 and so on are 2000$+Can… Otherwise you need to go into the cheaper lenses with the small and variable apperture and that's just a bit of a waste of money.

A good, general purpose lens is the Canon 24-70 f2.8.It's 1500$Can but is good for groups shots or landscapes, has an ok macro setting, has a good range for portraits, opens wide at All focal lenghts so is good for low light shooting and to blur out the backgrounds in portraits… It's just not very good for long distance shots like up close sports shots or bird watching.

Itisha, I'll answer your question like this: When it comes to technology it's always advisable to go for the most recent. So that one don't have to lament a few months later. So I'm proving here a link to the cameras that have been launched by Nikon, Canon and Sony in the past one month.
