As per your previous thread, I don't know what time period your enquiring about. But in a broad brush sweep, I can tell you arguably the best OEM transport mech ever made was the Victor XL-900 as used in the legendary Reimyo CDP-777. But sadly JVC stopped producing that transport. A few manufacturers are still using NOS Phillips CD Pro-2 LF which is probably the best remaining OEM redbook transport around. Though sadly production of that mech has also been stopped.
Esoteric are using the VRDS-NEO transpor mech. Accuphase meanwhile manufacture their own SACD drives in-house which is a smart move.
With your budget however, I would think this fully loaded Modwright Marantz SA8005 sacd player would be hard to beat. And it's dac performance would likely be good enough to sell your current dac - http://www.usaudiomart.com/details/649456359-modwright-truth-tube-mod-marantz-sa8005-tube-cd-playerl...
