DVD player recomendations

Ok I have a good one for fellow "goners" I have a Pioneer DV 414 dvd player that is probably close to 5 years old and looking to upgrade.My budget is somewhere around $5-700.00 and I am willing to bump it up to $1000 if the difference will be dramatic enough.I actually would prefer buying used to make my dollar go further.I am after a dvd player that will"smoke the doors" on my 414 in audio and video.SACD is not a important option or the DVI for that matter.If I can get some recomendations to get me started in the right direction,would be a great help.
Thank,Tim
