Take a look at this ebay auction -number: 230022321210
He got $1200 for "10 engines 10 cabooses (some of them are metal) 100 box cars + other goodies" as he states it in his listing.
The guy I called today wanted to give me next to nothing for the HO stuff I have. And did'nt care one way or the other about the "extras". Not even the track - 3 footers. Of course I didn't take him up on his offer.
