Also, for Advent, you might try the reflections by an amazing priest who died under the Nazi regime, Fr. Alfred Delp, in the book Advent of the Heart: Seasonal Sermons And Prison Writings 1941-1944.
You have time before Advent begins to order these.

The Swiss Guard carries these rosaries! HERE
There is someone out there who pretty much ripped off the idea, by the way. The link here is the right one.
