The Craftsman LT2000 is complete and turn-key, and comes with the leaf bagger attachment. It starts quickly, runs and cuts well, and is an overall excellent machine. The seat has separated, but can be fixed with some glue or epoxy (it’s currently held on by tape). The LT2000 by itself is $400.
The LT1000 has the hydro-matic transmission but has had the engine removed. The deck and seat are showing some wear, but it is overall in good condition otherwise. The LT1000 by itself is $150.
I bought these originally to motor swap and use the LT1000 chassis and transmission but have gone a different direction.
