I looked at the DayTimer website, the pens that look like they might fit are all ballpoints.... The LV Nails pen, while very nice, I suspect is a ballpoint as well (please correct me if I am wrong)... The $220 price tag is a little more than I was hoping for as well.... There is a Mont Blanc store at Woodfield that I may check out this week. If I cannot find anything suitable there I will probably go with the inexpensive ballpoint from DayTimer, and continue the hunt for a rollerball that will fit the tiny, tiny loop in the agenda....
