I assume you are refering to these PSC boxes? If it were me, I'd go with the PSC. They are upgraded much more than a simple rebuild and are ready for hydro assist if you ever chose to go that route.
I have been running one on my 04 TJ for a little over three years now along with Hydo assist. No problems with my box what so ever. BTW, parts are avalible for the PSC boxes.
