Replying to Studio Speakers

Yo NS, finally getting to build my work studio since I have a house at school now. Just got a second monitor and am currently looking for some studio speakers.

Don't want to spend more than $300.00 (Yes I know I probably should, but if I ever needed to do true sound stuff my school has a super nice room, this is just for personal stuff)

Looking to see what you guys suggest/have/ to stay away from. Anything is helpful because I know about zero. The shop near me had some KRK, M-Audio, and JBL that seemed decent but any remarks would be helpful.

Thanks
