Reply to controller decision

Now before you jump on me, i have searched a TON around on these community s for ideas and info.. But i would really appreciate it if you guys could help me out, my main focus with djing will ideally be house trance techno. I dont have any urge to do any scratching related stuff but i do want to be able to mess around a lot with effects, cause that what i want my djing style to develop into.. clean mixing with awesome added in effects.. Mainly, i would really just like to have a solid beginner controller, with or without a sound card because i can buy an audio 2 if needed, my budget is not big at all, i just have a few focused needs, solid effects capabilities, good build quality.. idk i guess thats it, the main controllers i have looked at are the mixtrack/mixtrack pro... the hercules 4-mx.. maybe the rmx? idk stuff that is in that price category, the 4-mx is a little high priced.. i would really appreciate input guys thankyou!!
