I understand that the Philips SACD1000 is a pretty decent player and can be improve through modification. I just perused this site and there are a couple for sale for around $700 used. You might try one of the lower end Sony players as well. You might want to ask one of the modders like Richard Kern (audiomod)or Jim Oade at Oade brothers. I am sure both of them will be more than honest with you.
