I went ahead and ordered a cute little Perigraphe, which is currently on the way across from Prague (per the tracking information from Ceska Posta). No complaints with the ordering and payment process; I'd describe their communications as terse but professional. I'll update when I have the order in hand, but since customs can take an unpredictably long time, I thought I'd update the thread now rather than risk forgetting it later.
Barring any unforeseen issues with the actual item, this has been a good trouble-free process. That's not necessarily good news, as I could get myself into a LOT of trouble feeding my nascent brass addiction this way!
