I like my 700-R4, but i upgraded because the 200-R4 blew up with flying colors, and nearly launched the pump through the pan. But thats irrelevant, yeah the 200's a nice transmission, but i think you'll get more out of the 700. Depending on what car you're putting it in, i can tell you the exact measurement of the drive-shaft cut, a local drive-shaft shop should be able to do it, and re-balance it for about 120$, and you don't need a new cross-member, just move that one and drill new mount holes, and pickup one of the adjustable transmission mounts , "Sliding transmission mount"
