Depends on how small or large of venues you expect to work.
There are many good options including the Motion Sound, as Terry said, the Logitech Z2000s (less than $100!!!), etc. EV makes some good options as does JBL.
In my opinion, the Barbetta Sona 32Cs make the best and most versatile system. But they are expensive.
You can search this forum and come up with many opinions, even though the past 3 months is missing.
