Driveshaft

I called my local dealer today to get the price on U-joints for my driveshaft and I found out that they aren't made for our car. I wanna spend the $1100 for the PST CFDS because I don't have that kind of money layin around. I know about the Aluminum 1pc. driveshafts that are being made and I might go with one of them if I can find no better alternatives. I really need to do something about this soon though because my carrier bearings are pretty bad and I don't wanna replace those just to end up buying a 1pc.
