At $99-$120, I wouldn't call them cheap.
But then again, I've never noticed the difference between the PS2 and all the other ones I've used.
With the higher priced ones ($150+), you get a whole slew of hookup options. The way I look at it, what's the point of Dolby Surround when a bunch have 5.1? Even the 'cheap' ones come with a optical out; what do you need the 5 a/v outs for? That said, the $350 players come with a built-in decoder. Which lets you use it with a reciever that doesn't have a decoder. But what if you get a DAT; it's gotta have a decoder too. So it's cheaper to buy a receiver that has a decoder in it, and use that for all your other devices.
Also, check out <A HREF="http

You're better off getting a good receiver ($350) and a cheap DVD player ($120), then vice versa.
