Heritage units phase I

I am in the market for the following Heritage units to complete all 20 in the series.

Illinois Terminal
Virginian
Savannah & Atlanta
Penn. Central
NYC
Lackawanna

I am still looking through my collection. I thought for sure I had the NYC unit but I have not found it just yet. I have many totes and stacks to go through. I prefer DCC but will consider DC units for which I can add a decoder.
