as a mostly prewar collector, it would be insane not to admit i like to find trains in the best condition possible, though pristine (i.e. new or like new) is extremely rare. my baseline is typically C7 or how i define "the best condition one could expect from something that has been used/ played with".
as far as new production, i'm glad it happened as it moves many collectors out of the market for operational models, but i doubt if i'll ever buy any modern tinplate models. fifty years from now, my models will be approaching 150 years old and still running while i estimate most new production will be non-operational shelf displays for want of an e-part long out of production or in the dumpster.
cheers...gary
