I hear you and I understand. That's the reason for getting away from the one I bought on an emergency..Mix, no offense, but if ur supposedly a master mixologist... you either don't know what the term means, or you're severely limiting yourself in what you're capable of doing it with subpar equipment. The equipment you keep referring to has terrible mixer low/mid/hi frequency adjustments... high end mixers use frequency isolators (or have the option of both)... and anyone that does proper beatmixing knows how to incorporate them into their mix. Also those lower end mixers have ridiculously bad platters with mediocre at best responsiveness, that if you're on the turntablist side of things, they wouldn't really allow you to reach the full advantage. That doesn't even cover things like loops, samples, scratching sound quality, Maybe you don't get out much and you don't really realize how much there is to learn. Put it this way, If you're a master mixologist, my skills must be pretty godlike then lol (but I am the first to admit, I'm far from it).
Now on the flip side it's about using what's comfortable to you. What one DJ can use and do a great job, another would do a poor job. My partner has the original Hercules controller. He used it at a wedding and did a great job. Me using it I would have done a poor job. It's not for me.
I once played at a club using a Numark CDN 25 and won a job there because I knew what to do. It was difficult because it doesn't scratch. So when setting up a mix all you hear is a stuttering sound. Real touch but I got by. I finally brought in my own CDJ 800's and mixer. Along with my EFX 500 so it made my job much easier.
Point being is you can have top of the line gear to work with. If you don't know what you're doing it won't matter. Also I don't scratch. I blend in the music on a smooth mix. Most times I get it right but I make a bad mix from time to time.
