Actually, the 1804 replaced the 1803 and would be an excellent choice to save you some $$$. Or you could move up to the 2803 for a bit more. (I'm a Denon guy). In this price range, the Denon and the other usual suspects (Yamaha, Onkyo, Harmon Kardon) offer pretty nice alternatives.

Some touchy / feely with a bit of research would help you make up your own mind. For these bucks, it really boils down to presonal preference. With the group mentioned above, you really won't make a mistake.
