Look, I have about as good a "network" for buying/selling/trading Clacks as it gets. I dare say nobody has a better one. Probably somebody has one as good as mine, but not better. I'm not bragging, I'm just telling you guys that I know what I'm talking about, and what I'm talking about is that NOBODY is going to sell you a Clack at the original price. There is no secret network of Clack owners selling Clacks for $35 to each other. Maybe somebody like bunnylake will sell one for $50, once or twice in the Classifieds to make a big splash, but that is to burnish his image in the community (and there is nothing wrong with that), but you cannot expect to pay the original retail price to get a Clack. That is just not realistic. At this time, almost every Clack in existence has changed hands several times, or so it seems, and after each transaction the price has gone up, because each person added a few dollars to the price he paid when he sold it. Is this a horrible thing? No. Now, there are some people out there who got Clacks in the very beginning for $8 and sold them for $80, but, I think by and large the people selling Clacks are not making huge profits off them anymore.
However, with that said, figuring out a "reasonable" price nowadays seems to be pretty hard. This thread is a good idea to try to figure out what a "reasonable" price should be. I don't have the answer for what's reasonable, but right now a Nightowl for $200 is a good price. I can tell you that. Even $250 is not "crazy".
