Weaver has been mentioned. In particular their TOFCs and the ones made for clubs. Many of those are bringing triple figures and most of the ones Weavers sold themselves sell for above list price and certainly above street price when new.
As for the particular K-Line UP Observation Sam started this thread with, its price got me thinking again of Lionel. I purchased a few of the most recent run of 21" cars and found them well built with zero flaws other than the gray paint being too dark for Harbor mist. Hopefully they have turned the corner with their passenger cars.
