$800 I'd look for a used top tier Mathews, Prime or Hoyt. Join archery talk forum. Their
Classified section is a great place to find a good bow for less money.
The Elite in our Classified section is a great option and less money than you want to spend.
Ebay Prime RVX34 can be bought new for $800 if you aren't set on color or exact poundage. That is a great option.
