which multi-disc dvd player of these, or other suggestions? (1 Viewer)

[Snowman3000]

As a birthday gift, I'm currently in the process of planning out a new home-theatre system for my parents. So far, I'm pretty set on the Pioneer elite VSX-82TXS for the receiver, as well as some Klipsch bookshelf speakers for front/back, klipsch center, and Velodyne sub. They currently do not have a HD TV, but it'll come not too far down the road after all the audio.
What I need to pick now is a multi-disc (3 or 5 disc) DVD player. It doesn't have to have all the newest and best features, but I don't want anything that will need replacing in a couple years because of lack of features. My budget probably caps out at $300.

So far, my short list is comprised of:
-Onkyo DV-CP704 link
-Sony DVP-NC85H link
-Yamaha DVD-C750 link

Yamaha has a few more, but this one looked best in my price range.
Does anyone with more expertise than me (doesn't take much) have any input as to which of these would be best, or have any others to suggest?

Thanks in advance.

Onkyo and Sony Models look very simular in specs. 720p/1080i upconversion and HDMI output.

The Yamaha I only see Component Video and Progressive Scan (480P) output.
