I am looking at getting these too...
I haven't heard them but from what I gather, they are not professional monitors... but are very good for a home-recorder or hobbyist recorder...
fact is alot of people doing home recording simply cannot afford the high end studio equipment... this is where M-audio has seemed to have stepped in... making high quality recording equipment at prices even us simple folk can afford.
Hey... they'll be much much better for mixing than my computer speakers I'm using now...
P.s. I also like that they are shielded for desktop monitoring in mind... I like this since they will be placed beside a computer monitor for me..
So far, the only place I've seen on the web carrying them is SoundChaser for $299/pair...
