search the for sale threads once u get more involved in the site and get ur post count up

 

Your not going to do much better on the price. Most that are selling them used are getting like $650. Every once and a while you'll run accross one for less. I just saw one here in the for sale section for like $550 but that was an exception not the norm. Good luck but to me its worth $50 more to have a warrenty.
