look for dynaudio, tannoy, yamaha, mackie, adam, and jbl to name a few. certain of the models will give you an accurate sound and will provide the low end, which m audio has been criticized for lacking. for small speakers but not the main ones, the auratones have been raved about.
monitors are a subjective thing so make sure and hear them 1st. bring a reference cd and hear what they sound like with your favorite songs sonically. if you can't, see if there's another store or a studio that uses any monitor you're interested in and inquire whether it's cool to check the studio for possible booking, then preview the ref cd in their monitors. your place might not have the same treatment as the studio but you'll get a good idea of the sound ad response, as well as, seeing whether the studio, big or small, would be a place worth tracking at in the future (some have horrible acoustics despite the size, some have effed up the wiring or don't have sufficient monitors for a type of music, either too coloured or lacking certain things like bottom)
