I would let it be known you are looking for a LCII and see what turns up over time.

Both my LC3's were free ex school computers somebody hoarded and got rid of later. Most people would want a LC3 and later because of speed and RAM, so if you realy want an LC 2 then you might have to wait a while since they are not as common.

I would probably get a dual floppy version just to be different and run OS 6 on it.
