Panasonic BD-30 v. Oppo upscaler DVD

[chasarms]

I am mostly disappointed with the PQ of DVD on my Panasonic plasma. (50" 1080p) I am curious if any one out there has a very good quality upscaling DVD player and can comment at all of it's performance against the BD-30 when playing DVDs.

Of course, I will buy BDs for every future title and probably even replace my DVD collection as the BD becomes available. But I have a significant collection of DVDs that I don't expect to become available on Blu for a long while.

I have read more negative than positive about the BD-30s ability to upconvert. What are the opinions of it verses a premium upscaler? Would it be worth it?

I am perfectly willing to accept that it is the nature of the DVD. I understand most of the science of resolution, bandwidth, etc.
