Reply to DDJ-SX or CDJ-700's

I know this really comes down to preference, but I'd like to see what you guys believe.

Option 1:
A pair of Gemini CDJ 700's and a good second hand 4 channel mixer. This set up would be strictly for home use and practice. This would be good because I believe that it would help me be more familiar with a club setup. I've owned a pair of numark ndx-400's and shitty numark m4 mixer, but I still believe if I were to show up to a club with cdj 2000's and a djm 800, I would be lost. I do alot of house parties and small outdoor events, but I'm really trying to break into the club scene. We have alot of good clubs here, and I know all the right people.


Option 2:
The Pioneer ddj-sx. This looks like everything I have ever wanted in a controller. This would be awesome, because I do really enjoy playing big house parties and doing mobile gigs. Not only that, but it seems like I could record some awesome mixes with this thing and really have some fun with it. The past year I have been using a mixtrack pro and feel like I'm djing with a childrens toy.


So I guess it's either Nice home setup for practice and keep my shitty controller for my mobile gigs, or I get the ddj-sx and wait some time before I can afford a good bedroom setup that I can practice on for the clubs.


Thanks in advance for the replies!
