Actually, Chebby, I think you should buy one.
It would be more than technology for technology's sake for you. First of all, the quality gain to your DVD collection's picture would be quite excellent. Secondly, you'll be free to buy a title on BluRay and start, at least, to move over to that format as and when it suits you.
If you bought the forthcoming Oppo 831, then you'd not only have one of the very best DVD upscalers (in my opinion) but you'd also have a deck capable of outputing via coaxial or optical or even 2 or 8 channel analogues to whatever amp you have. Simply put, I can't see how you could lose.
Now, you may come back and say, I'd lose 450 smackers. I think this is the part when you make the choice to upgrade. And it would be an upgrade. From the moment you put your first BluRay in you'll notice the clarity of the picture, the depth and increased width to the sound. You need high end speakers and a good amp to make the most of it, but the benefits of the Oppo are many, including SACD and DVD-Audio compatibility. Now you may say, you don't have any or couldn't care less, but frankly I'd be surprised if that were true as you're on this forum.
More than anything buying a BluRay player and particularly the Oppo because of it's universal player credentials, opens the door. As morpheous said, "you're the one that has to walk through it." Hope you do but you have my full respect if you don't.
