Need Opinions on PA Mains

I am just beginning to research investing in a PA for the cover band I am in and I need opinions from those in the know on live sound. One of our members and his PA parted ways with us and we've been using some old Yamaha passive speakers in our recent gigs. They sound fine but they are HUGE and bulky. I have decided that it would really be more convenient for us to just go with 2 powered mains. Our gigs are typically less than 200 people and we only play a big room maybe once a year. Also, we are only running 3 vocals, 1 acoustic guitar and sometimes the drums (depends on the venue) through the mix. Other guitars and bass have their own amps. Here's what I am looking at:

Electro-voice ZLX powered 15's

Anyone have opinions on Electro-voice or would recommend something else?
