I recently purchased micromax canvas 4 G
Good things: I like its camera which is about 13 mp. If u low budget want a good clear camera it is good option or you are selfy freaky then it will fulfill your need. also a good performance with 3 gb ram so u also play a big game also which need more ram to play.
Bad things: Battery becomes soo hot when I pluck in charger I don't know why it is but I use nokia 501 earlier & its battery so awesome and required less time to charge
