The MP one is 'close enough' for me to at least not choke. I've come close to getting one several times before, but it would be another shelf queen and I already have too many of those.
The ones that make me burst out laughing is anything (primarily Tyco or Lionel) that use CHROME in place of silver/stainless paint on F-units, GP40's, high-nose Alco C630's, you name it. And to think that entire mess evolved out of the U28CG scheme. Remember the real red and silver warbonnets (GP60's, etc.) didn't appear until decades after Bachmann had been painting GP40's by the shipload in a scheme that didn't actually exist (red and silver with the black and yellow separation stripes). The U28CG was the only hood unit ever painted in red and silver, no separation stripes, until the SuperFleet era of the 90's. From 1966 to 1989 (23 years!) nothing else was painted that way. In the 1970's Santa Fe went out of the way to kill the red and silver to distance themselves from the passenger era, at the same time the modelmakers were churning them out by the thousands.
I'll always nominate the Bachmann GP40 in full red and silver warbonnet as the original Great Foobie, multiscale, helped started a trend that copied on the real thing. If you don't know the story:
