HU Reccomendations

i need to get rid of my sony.. heard too many bad things to keep it for my new car. as soon as i can get rid of it ill need another. id like to have one in mind so i dont have to drive without a stereo long. want to spend about 150-250 (after shipping if its a factor).. i need sub preouts (or at least controls to isolate most of the bass from my speakers yet keep the sub hitting hard) mp3 or not, dont care. probably not going to run an amp to my speakers, if that matters. the cheaper the better.
