I work for guitar center. Email me and I can get you set up(its at the bottom). There's a lot of set ups starting at the very lowest with the speakers youre picking out, but staying in the low end it goes upward towards 400 for a pair.
Usually I recommend spending at least three hundred if you want closer to accurate playback.
Of course keep in mind placement of speakers and the room you're mixing in have a HUGE effect on the sound you're hearing as well. Isolating speakers from table is a must, and so is creating an equilateral triangle with the tweeters and your head. I wont even get into absorption, diffusion, and soundproofing, nor resonating desks and other studio objects...
TLDR; I can arrange so that you get speakers via an active promotion and get em shipped to you so you should contact me.
