I like the streamlined K-2 quite a bit. Were I earlier in my "buying arc" I would have reserved one. This is an example of a noteworthy piece being so overshadowed by its Famous Sibling that even people who should have known better and reserved one did not do so. I'm looking at you, N&W geeks. Shame on you.
The previously-produced 3rd Rail product did not help, either. It had soaked up most of the weak streamlined K-2 mojo already. The Lionel piece would probably have been the superior product, too.
Lionel: if you want to sell me your K-2 prototype, e-mail me....couldn't hurt....
