Why eBay? Try other "sources". I got it, and it's not bad actually. The music is still shit, but great in 5.1.

Or, try TFM Audio tool; I converted "These Days" to a 5.1 upmix. Results were incredible (just set the surround delay to 0ms and let your seyup handle the delay.

It creates a 5.1 DTS .wav file for each song - just burn as a regular audio CD with Nero and enjoy.
