I think with all the baby boomers retiring they are buying their childhood trains, as the prices for Vintage Post War has been going much higher than usual.
I even gave up on getting a 2344, 2356, and even just a motorized chassis to finish up my 2245.
For what they want for these old trains, I would just rather buy the Lionel re-issues with all the Bells and Whistles.
For example, my new 2245 Post War Celebration Series with just TMCC, sounds just like the vintage on from a "growler" perspective, in fact it sounds better, looks better, and I paid less for it than a vintage one.
I guess, unless the Vintage Post War train of your liking is part of a "gotta have" because you had it as a kid or always wanted it as a kid, it has even for me who started collecting, to just give up on it.
