About studio monitors...
Behringer is a copy of Genelec, not Mackie.
If you listen to in far-field or "mid-field" and not close-field, consider getting a pair of monitors that :
A) have good optimized wave guides (e.g. Genelec, Klein+Hummel, JBL) and not something slapped-on without a brain (Behringer, Mackier, many cheap brands). This is to optimize directivity and to control it (not too high a directivity index, but high enough so that first reflections are minimized)
B) have proper high-frequency roll-off filters (so you can adjust high-frequency amount based on your room's response)
C) have enough power in the amps to drive the speakers without clipping, distorting or making the elemest sound strained
I've heard the Behringer's, but haven't compared straight head-to-head with good known ones (Genelec, Klen+Hummel, Dynaudio, etc).
I think they are very decent for the money, but I wouldn't buy them, just because they're almost 1:1 copy of another loudspeaker.
If you buy monitors for monitoring and not just home use, consider also the replacability of the parts (particularly elements) and their availability. Good pro studio monitor makers still service and offer parts to their loudspeakers that have been out of production for over a decade.
Grab-the-money-run-companies offer no parts, no service and you buy a new pair is something breaks.
Just my two cents worth.

PS I'm biased towards Genelec, Klein+Hummel, Dynaudio and JBL (the newer models designed with Harman intl. blind listening test system).
