I think you should buy this kit if it suits your budget

and
Ebay is not opening the battery page
I think you should buy battery from robu.in or vibranthobbies.com
tx and rx from rcmumbai.com
It's upto you cause this kit is cheaper than taking individual parts
You can contact satya sir ( owner of quadkopters.com ) and clear any of your doubts regarding it
I think this is the best kit you can get
