I used a Musical Fidelity V-Link in my system for a while. They can be had used for $75. They had a version II that has a higher bit rate for a bit more cash.
As for CD players, the ones that have a USB input will allow you to use the built in DAC for things other than just the CD in the player, which is great. If the CD player in question does not have a digital output, then you are stuck with the built in DAC.
As you move up the food chain, you will find CD players with digital output as well, which give you the option to use it as a stand alone player or with an outboard DAC.
Out of curiosity, what are you going to do with the USB-SPDIF (Coaxial) converter?
