Get something with Pro Logic II. This is one of the biggest improvements I've seen over the years. Other things to consider: stay away from receivers with different power rating for different channels, ie 60 right and left, 30 center and rear. This is usually the sign of an older unit. Also, keep the remote in mind. Some are much nicer than others. Many Denon, Rotel, Marantz, Sony ES and more will fit the bill.
