I've recently acquired the Norfolk & Western set, the SP 4449 set and the Alton Limited.
More or less new in box. I really like them. I've always been a tinplate guy but I just can't stop picking up some of the nicer MPC era stuff.
I'd really like to add some more of it to my collection. I knew I was in trouble when I bypassed the prewar section and went straight to the MPC section at my local train shop!
I'm hoping to get that Wabash set soon.
