Honestly I'm leaning more towards the Hack N' Tap kit. simple and cheap. I like the yoke much better than a flange that some kits have.
I'll have to think about it though, cutting the output shaft perfectly straight and tapping a hole under the Jeep is probably more work than just replacing the whole shaft. Does it come with a new speedo gear?.. Did you install this with the transfer case in the Jeep?
