I am not sure if the 200R4 is still being manufactured new or not.
I did some research on the subject (200R4vs. 700R4)as to which would be the best swap for my truck and read some very good articles as well as several comparisions with all the transmissions.
But, after doing some search's, I can not seem to find them yet.
Here are a couple of links...

Here is a pretty wild web site dedicated to the 200R4..scroll down to the bottom for the gear ratio comparisons...
