Most any 6.1 receiver on the market today will have ALL the features you listed, from the $250 Pioneer 812K to the $775 Pioneer Elite 45TX. The features you mentioned are pretty standard across the board. When you transition from the $250 - $500 range into the $500 - $1000 range, you start to see large improvements in sound quality and more specialized features added (room adjustments, video conversion, ect). What you need to decide is weather you want to save money and get an entry level receiver that fits your criteria, or go up toward your spending limit and get a receiver that has better sound, better build, and more specialized features. Alot of this will depend on what speakers you match with the receiver. Most members agree that you should spend more (up to 2 times) on your speakers than your receiver. Better speakers will make a more noticeable difference that a better receiver in most cases.
