Reply to First CDjs and Mixer [Help]

I have always wanted to get into a DJing and start mixing my own house music and have finally decided I'm going to invest in some gear .

I have been shopping about and I believe I am going to get a pair of NDX400 but I am unsure what mixer to get.

Any suggestions on a mixer and are these CDjs okay.

Also what should i be looking for in a mixer.
