CE series 4000 rock. Much closer to the K series. CE 1000 and Ce 2000 are budget models.
Do you need subs? how large a venue are you playing? Minimal good sounding for rock band is dual 18"'s per side, or quad 15"'s, good top end full range EAW's , Reinkus mid range line. Allen heath board is good for money. One ce4000 per sub, one for the tops. You'll be into about 10K for a good entry level setup.
If you want to sound like every other under powered club band out there get the Mackies or the EV's.
Just like studio sound, you get what you pay for.
