SO happy to hear lots of new excitement for Due South! I am currently in Vegas and short on time, but I'd be happy to make recs at some point. If you want, you can check out my recs page at http://justbreathe.mediawood.net and then Recs - all Due South recs and mostly NOT the authors you've already dug into (I love them all, but tried to rec some less known stuff as much as I could).

Enjoy! While I'm slowly falling out of DS, I love to hear about those of you who are just discovering it. *g*
