When you're in this price range, the room you're in is more important than the monitors you choose. You're probably not going to get a decent image of your low frequencies with any of these monitors, so just go to a store with some different monitors and just go with whichever ones you end up liking more. I'm not saying that all budget monitors sound the same, but they're all pretty inaccurate.
Unfortunatly, you have to use the shitty shit to find out why the good stuff is so necessary.
