i own a pair of behringers (8" woofers, 2031A i think) and they are a good place to start vs home audio speakers. i would encourage you to get the 8" ones for some slightly better bass response. you would probably do just fine with the MAudios too, but i can't vouch for them and you won't get the bass response that you would with the behringers (particularly the 8" ones).
to speak on monitoring in general, a lot has to do with your environment and far more how you "learn" your monitors. by getting a pair of studio monitors, you are heading in the right direction since they are all designed to reproduce the details of sound vs. pleasant sounding music. frequency response flatness is only one part of the equation, the other is responsiveness of the speakers which determines how finely the details are reproduced. however, all that is for naught unless you train yourself to listen for these details and make a connection between what sounds good on a well-mixed/mastered album and your own mixes.
i've spent years mixing (even with the behringers) and while i've gotten better, i can still quickly embarrass myself by playing my mixdowns in a car stereo. part of this is my mixing environments haven't really been that conducive to picking up the subtleties of low end frequencies, but most of it is that i don't have the experience (and probably, talent) to translate what to me sound like pretty subtle differences on the monitors and pretty big ones on my stereo.
i say all that so you will have the proper expectations and not be disappointed that your mixes don't sound "good" - they will probably get a lot better, but they most likely won't stand up to a commercial mix until you keep at it for awhile. comparing your mixes to commercial ones is the best way to learn, as well as listening on different consumer systems (home stereo, earbuds, car stereo, computer speakers, etc.). the important thing to do when comparing is realize that louder sounds better, so you need to turn the commercial mix down so it is at a similar level to your own mix (or turn yours up).
good luck with your monitor purchase - and this is a great place to come for advice. a lot of pros hang out here (i'm not one of them, i'm just good at learning and writing, vs. actually doing

) and can tell you even more about the fine art of studio monitoring.
