Hey, here's another thought---check the Cascade website's classifieds. I've seen used tandems for sale there too. You know we got our 91 Burley at Recycled Cycles for $350. We were very lucky. But I would hang in there looking for a used one because I agree---I think there are frequent sales of those.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
