Reply to Mackie 450 V2 - Thoughts?

I'm looking to purchase a new set of speakers. Found a guy selling his pair of barely used Mackie 450 V2's. Looking for honest thoughts on these loud speakers. Are they worth it? Is anyone else using them? Is there something better in the same price range I should be looking for (+/- $1000)?

I appreciate the input.

Thanks!
