New Mp3 Player -- Anyone able to give comments on following 'maybes'

Hi,

I'm trying to come to a conclusion over what CD/MP3 player to buy for the car.
I have been looking at the following six and am trying to come to a decision. There don't seem to be many reviews about them on the
net, and so I would be most grateful if you could tell me what you think of your Mp3 players if it is one of the following:

JVC KD-G401

Clarion CLA-DB348

Kenwood KDC-W4527

JVC KD-S891R

Pioneer DEH-PS600

Kenwood KD-CM4524
------------------------------------------------------------
I am after a Headunit that meets the following criteria:

*Able to play all MP3 bitrates between 128kbps - 320Kbps. I know the Pioneer can do this but am unsure about the others.

*ID3 Tag support. I know that some of the radios here have the ability to read tags but I have heard some show only the first eight
characters or along those lines. Could you give me more details on your HU.

*Removable Faceplate for security reasons.

*Disc Folder Support. I know the Pioneer can handle this.

*Option to play tracks randomly on CD/MP3 disc.

*Bass, Treble Balance options.

Could you also let me know if your HU has:
*EON
*Clock

Most grateful.
