Reply to Another which CDJ thread for home practicing

At home i use Traktor with timecode vinyl which i will use in clubs also
but i really would like to able to work with cdj's.
So i'm looking for a cdj,only for practicing at home.
I don't want to move it around use it on a party or whatever just home.
But i want a cdj that comes close to club standard cdjs just in the way of working with them.
No effects,just the way of working with them.
What do you recommend?
Is the 350 enough,850 the way to go or is even something like relloops RMP 2.5 or 3
enough for practicing at home?

Thanks in advance
