What Camera to choose ?

Hi,

I've a great interest on photography but still am a beginner. i am currently using a Sonly DSC W360 Digital Camera and take pretty decent photos from it

(check some of them at http://www.flickr.com/photos/93737207@N06/)

I am hoping purchase an advanced camera, but am quite confused as what to buy.

well, the maximum amount that i can afford is 400 USD, hence i have no choice but to settle with a hybrid camera.

here are my choices

Fujifilm HS30EXR

Nikon Coolpix L810

Sony Cyber-shot DSC-HX200V
Panasonic FZ200
Canon PowerShot SX50 HS
After doing a slight research i think i am liking the Fujifilm one but i need your opinion as well.
Here are the list of questions :1. Which Bridge camera is suitable for me ?Canon EOS Rebel T3) will be meaningful ?  i did some comparisons between Nikon D3100 and Fujifilm HS30EXR; apart from the interchangeable lens, Nikon D3100 didnt show any advantages. Besides, Fujifilm is not expensive too2. Do you think going for a Entry Level DSLR camera (Nikon D3100 or 3. Can you fix Telephoto lenses to Fujifilm HS30EXR ? according to amazon, you can. but i need your comment on this (http://www.amazon.com/Proffessional-Special-Telephoto-Fujifilm-HS25WEXR/dp/B008UYU4SG/ref=sr_1_2?s=electronics&ie=UTF8&qid=1362301166&sr=1-2&keywords=Telephoto+Lens+Fujifilm+HS30EXR)
I am not a frequent traveler  but don't take chances to miss capturing beautiful scenes. i am kind of a macro photography fan too.
Please Guide me !
Thanks alot !!
