Best Upconverting Bluray Players If You Could Pick Only One Blu-Ray Player?

If you could pick only one Blu-Ray Player? - best upconverting bluray players

I have an HDTV in 5 years (Toshiba) and I still have an HDMI input on it, but I get a Blu Ray. Therefore I must use the RGB cable to my TV to watch Blu-Ray. So what would be the player that you would advise me the best picture, also have about 300 movies on standard DVD, then I would really like a Blu-ray to make a decent job of upscaling (if possible) DVD. I appreciate your recommendation, after a brief explanation of why he was chosen. Thank you for your help!
