I second getting Ethan Weisgard's books " Bukiwaza." I have seen them and they are written very clearly. I really would like to buy a set but I feel that they are prohibitively expensive.
My understanding is that the Saito sensei set from aikido journal is a re-release or later edition of an earlier work. The earlier book set is said to be a classic. I have only seen the newer edition and its pretty detailed.
If you can get your hands on Aiki Friendship demonstration DVDs, there are classic displays of Saito sensei performing the kumitachis and kumijo practices on there.
