I'm partial to Shelley as well.
If you want something more overtly Reformed, check out the lecture notes (PDF format!) that accompany Dr. David Calhoun's two church history courses available for free from Covenant Seminary (Early and Medieval History -
http://www.worldwide-classroom.com/courses/info/ch310/; Reformation to the Present day -
Worldwide Classroom: Reformation and Modern Church History). I listened to the MP3s on my way to and from work and found them a GREAT introduction or review. The transcripts and the study guides are a wonderful resource. And, thanks to the good people at Covenant . . . ALL of them are FREE!!!
(BTW - While reading the Institutes in this special 500th anniversary year, I'm currently working through Dr. Calhoun's 26 lectures on Calvin's Institutes. He is quite good and easy to follow.)
Chris, you beat me to it. We were evidently thinking the same thing at the same time!
