Which are the desireable 2004R's

Is a CRF one of the good ones???? What others...

What do you mean by "good"? They are all basically the same except for programming ie. valvebodies/governors/intermediate servo.

Good question, also would like to know if the TCI street fighter is a TR 2004r(originally)

You pretty much have listed them all. This website shows all the desireable ones in bold. One that is supposed to be pretty good are also the AA trans from cadillacs:

As far as I know the TCI trans are not original TR trans but have modified valvebodies to closely resemble an original.
