Hi Binary.
The advice that Doc gave you is quite sound, pardon the pun.
My interests and knowledge base center more around studio/broadcast equipment which is quite different than live sound reinforcement, however I'd be happy to chat with you if you still wanted my opinion. My main advice would be pay a little more for good equipment from someone who will be there when something stops working, instead of saving a few dollars from someone who'll say "sorry, we don't carry brand XYZ any longer.
Feel free to post or pm me with what you're thinking of and I'll see if I can be of any help or not.
Good luck.
