Collins CW filter
 

A 200-Hz crystal filter for the Collins S-line went up to 300$ (see http://cgi.ebay.com/ws/eBayISAPI.dll...544&id=&sasel=)

300$ is just the price that Rockwell today quotes for reproducing any Collins S-line mechanical filter (though I am not sure whether that price also applies to the crystal filter).

The e-bay madness is partly caused by people not having yet appreciated that bidding days before bid end does nothing else that raising price. Why? Simple, because it is very common to run into one of those guys that want to appear as the high bidder at all times. You bid, and he will place incremental bids until he gets above you. You bid again and he will again bid until he gets the high bidder. An endless loop.

If everyone would only put an offer by the last half minute, prices would get lower, on average.
