Looking forward to it also. I really need to hone my understanding of the bond market. 6 bucks used on amazon sounds good to me also.
A book I found that was recommened a few times(forget where at this point though) but haven't purchased yet is:
"Bond Markets, Analysis and Strategies" by Frank Fabozzi
http://www.amazon.com/gp/product/013...d_i=1428808175
Quite a tome at almost 800 pages.
