Which one would you choose to start taking pictures?

I need a camera to start off taking picture in a very amateur way, I'm just starting but I would really like the Camera to have the best performance, so far I've been looking on internet and i learned about BRIDGE cameras and DSRL, I like the following, please tell me which one would be better for me! Thank you!

-Bridge:

-Canon Powershot SX50HS

--Panasonic Lumix FZ200

-DSRL:

-Nikon D3100

people say that the last one is better but buying different lenses is not something I can afford, so I don't know if different lenses would be necessary for the last one to work!
Thank you!

Added (1). Sammmeh, what about the lenses?

I would choose the Nikon D3100. I really like it. I take pictures i'm just starting at photography and i use it.

Nikon D5100

Nikon D3100 all the way, its very reliable!

If your just starting out, then this camera isn't too hard to use, once you get use to this you can upgrade to other models like the nikon D7000.

Josh, back in the day we bought 35 mm film cameras and a 50 mm lens and our only "zoom" was our feet. Unless you are about to shoot weddings, wildlife or sports, I feel you can be very happy with an 18 - 55 mm lens. If you have the option of getting a zoom that goes to further, even better. Bridge cameras, however, I feel are outgrown quicker. Just my humble opinion.
