Reply to Beginners controller, 500$ budget.

I have a budget of around 500$. Would like to buy 1st controller. Thought about mixtrack pro 2. But its quite small ( i have big hands ) and might be useless after few weeks because of lack features. I have good motivation to get in dj business, so i wont let it go after few tries. Thats why i believe about numark N4. Its bigger, and will be longer up to date, to train more skills. Any advices ?
