Time Life Classic Jazz

This morning while reading the newspaper and listening to ESPN, the commercial for this collection came on again. I flipped over to the Time Life web site and took a look at it. It is one of their typical buy the first two discs, then get another disc every month. The total set consists of 10 discs for a total of about $110 currently "on sale" for about $94.

Has anyone listened to any of these discs? If not has anyone listened to any of the other Time Life discs? What is the quality of these recordings? Thanks :-) Doug
