The marantz 7200 is an excellent choice. It has 2 sets of component inputs. It has also been recently been discontinued so you should be able to find a great deal on it. It has all the features your looking for. (6.1 inputs, 100watts x 6, plenty of inputs, good little LCD universal remote.) I paid $600 for mine. If you want to spend more the SR8200 adds THX Select, 120W x 6). But it still only has 2 sets of component inputs.
The 9200 has 4 sets of component inputs, but is probably out of your price range.
