the reveals are a great bang for the buck speaker, you should be very happy with them for quite some time.
Make sure you set them up well. Also check out how some other folks suggest the alignment of the speakers they make. there is some good downloadable info at the Genelec site and the BBC white paper stuff is always interesting if your really a geek.
Anyway take the time to set them up as best you can, that is as close to the ideal setup as you can come up with.
then spend a lot of time listening to other mixes and your own and get to know what your mixes and such sound like on other systems as well. You will get to know them and thus your mixes will improve greatly.
i use KRK's myself but am thinking of getting a pair of Reveals for getting better sweet spot when programming the synths and leave the KRK's for monitoring when mixing.
