I prefer the transport and DAC seperates because of a few things. Better isolation, better flexiblity, easier to get a high quality transport mechanism and high quality DAC chips. Cheap - I would recommend a used Aragon D2A2 DAC, they have excellent build quality, sound, and service. Think I saw one recently on gon for about $400, then pair with any good CD player as the transport, or get a seperate transport.
Moderate price I have and like the NorthStar 192 Transport and DAC list $5,000, but can pick up new for $2,800 for both, or used for about $2,000
