Hey DJTT...

So. Right now I'm running traktor 2 pro with a numark mixtrack and midifighter classic, macbook pro 15" and a NIO 2|4... a nice lightshow and a nice soundsystem. I run a mobile dj business and have had quite a few gigs this past month.
My problem isn't the music or lights or sound or dj's (me and my friend)... but our controller. The damn mixtrack, as great of a beginner deck as it may be, just makes ME feel really... cheap and unprofessional. It does work.. and pretty well, besides the tactile buttons that just give me hell (though the left jog has been a little TOO sensitive recently... 'specially when we spin a dubstep track with lots of table shaking bass...).
I'm wondering... Is it worth it to sell my mixtrack and soundcard (I figure I could get... 250$ for them both?) and upgrade to something that looks, feels, and responds with a little more beef? Back in my gear shopping days (when I was oogleing over the mere thought of having a pitch fader...) I loved the Numark Mixdeck and what it seemed to offer. After more recent research, however, it seems like the Mixdeck is not what I thought it might be... kinda cheap, problematic, and not awesome. I love the pioneer CDJ's... but they're way out of my budget of <$600 and they don't all have midi functionality...
Do I just have massive GAS or is a small midicontroller slightly unprofessional? And if it is worth the money... are there any good beefy controllers that feel, look, and respond better than the mixtrack?
