With so many 390E's from MTH, I thought it might be kind of interesting to take a look at the original from Lionel. It's actually one of my favorite locos. It can negotiate any curve, isn't especially expensive and can pull almost any freight or passenger set. Not much downside really other than it isn't a Hudson or truly reflected by a protoype.
What's the rarest 390E? Is there such a thing? I'd guess it be either the green or Blue Comet 390E. Is there something rarer?
