Best Upconvert Blu-ray Any Difference Between 1080i And 1080p Upconverting DVD Players?

Any difference between 1080i and 1080p upconverting DVD players? - best upconvert blu-ray

I have a 1080p upconversion TV and just bought a DVD player with upscaling to 1080i. DVDs look much better now, everything. I wonder whether a player who can convert the 1080p picture, or better yet, if the difference is negligible. (And, oh yes, I know that the best thing to do, just to Blu-Ray or HD-DVD, but not in my price range for a while, so I would rather spend a few days dollar now the best picture receive, we can leave my current DVD).
