TD-1200 was the first generation TD-1200
TD-1200 mk II corrected some of the 1200 issues -- cannot remember what they were, but the 1200 mk II is prefered.
TD-1200SE as indicated in an earlier thread has an Aux input and reported better preamp section. All these decks show up from time to time on Ebay, but be forewarned that they are all now in the 20 year old range and were finicky when they were brand new, even. They are definitely a piece for the enthusiast. The FM was not very good, but the cassette section was fantastic.
